Design And Development Of Boost A Converter Using Planar Inductor For Dual Supply Automotive System

Today, innovation in electronic automobile components has resulted in the need for higher voltage power supplies. In future automotive vehicles will have 36V operating system. In order to convert to 36V operating system, a 14V/42V dual power supply design is currently being tested and implemented in electric and hybrid vehicles. In future all electrical and diesel vehicle components will be using 42V electronic components ( bulbs, alarms, radio, ICU etc). Boost converter 14V step up to 42V will be an essential component in all vehicles. This work comprises of designing an efficient boost converter which can be easily manufactured and will work for dual supply electrical vehicle as well as diesel vehicle. Current available electric vehicle converters are either buck or bidirectional type. Various topologies have been used in electric vehicle converters. In the early days, auto-transformer topology was common, followed by toroidal inductor which became popular. Currently E-I planar core with spiral PCB inductor are being gradually applied in industry. Jumpstart post embedded in the converter is another key area of electric vehicle converters with dual power supply being studied. The scopes of this research are to evaluate and experiment ideas before building and testing a design with auxiliary start (cracking) aid boost converter that would be compatible the 14V/42V power net. In this research dual supply vehicle boost converter prototype designs were experimented. The work consists of design study of CCM DC-DC Boost Converter with E-I Planar core spiral PCB inductor using a SMT UCC38C43D PWM chip controller. The experimental results are obtained using the Planar spiral inductor DC-DC boost converter, designed to operate in CCM for 120W with an efficient of 85% and output voltage ripple of 5%

Energy Monitoring And Power Quality Improvement Through Smart Metering In A Home Based System

There has been a tremendous increase in the use of variety of electrical equipment in industries and various types of electrical appliances in residential and commercial buildings. There is also an increasing trend in the use of distributed renewable energy sources. Many of these modern equipment/appliances and renewable energy supply systems involve the use of complex electronic/power electronic circuits which result in considerably high harmonic pollution affecting power quality and energy losses. This leads to a need for improved energy monitoring, reactive power compensation and harmonic filtering at the terminals of the loads and/or at the power supply entry points for energy conservation and power quality improvement. This thesis deals with contributions to improved energy monitoring, reactive power compensation, harmonic filtering, protection and demand management incorporating IoT/IR4.0 concepts. The concepts and methodology proposed have been tested and verified by simulation and hardware implementation in single phase systems. The proposed concepts can easily be extended to three phase systems in large residential and commercial buildings and in industries. Many of the existing smart meters measure the rms values of voltage and current, average power and power factor only. Some meters also measure total harmonic distortion. The design and development of an improved IoT based smart meter is presented in this thesis. The proposed smart meter enables waveform data logging and detection of unique load signature in addition to measurement of voltage, current, power and power factor magnitudes. It also enables, clustering of electrical equipment for cost effective reactive power compensation, power quality improvement and demand management

Fuzzified Single Phase Automatic Sequential Reactive Power Compensation with Minimized Switches

The current rapid growth in IoT technology facilitates the effortless implementation of bidirectional remote monitoring and control system implementation in homes and buildings. We have modeled an actual non-intrusive PnP sequential SVC prototype hardware and wireless FLC automation software design on a real single phase home appliances system as load modeling. In addition, we have also designed a novel Unidirectional MOSFET Switched Capasitor model (UniMosSC) which enables us to reduce the hardware cost and increase the life span of SVC due it uses minimum switching devices. The system we have designed is able to correct the power factor at the root of the problem at each appliance. Due to complexity of appliance clustering and overlapping clusters, we implemented fuzziness in the system for more reliability in computations. The system could be used in homes or buildings resulting in electricity bill reduction, saving dollars and cents

Modeling a UNI-Mosfet Switch for Single Phase System Application

The concept of replacing mechanical switcher using Solid State Devices (SSR) as the medium of relaying high power AC load has already been recommended five decades ago using Dual Thyristor or Triac. The rapid growth in SSR field has now resulted in using dual IGBTs, dual JFETs, dual MOSFETs or dual HEMTs semiconductor devices to control high powered AC loads. One of the drawbacks of all the systems above is that they all using two semiconductor devices to operate for both half cycle of the single phase AC waveform, with either anti-parallel or anti series-arrangement incorporated. We have modeled a novel SSR, using only one MOSFET semiconductor device with a new SSR module packaging. This novel Uni-MOSFET SSR is capable of operating on both half cycles of an AC waveform and eliminating problems associated with dual semiconductor SSR system. Moreover, in this paper we have explained the simulations proving that the Uni-MOSFET SSR is able to control resistive load and able to compensate capacitive and inductive as a SVC, which is as good as its predecessor the Dual-Thyristor SSR. The draw back would be the complexity of the control signals of the Uni-MOSFET SSR for TCR but we have managed to simplify using equations. Our novel SSR is cost efficient, low noise and works well as a load switcher, circuit breaker or compensation switch for single phase electrical network system

Smart Home Meter Profiler with Load Authentication, Shock Protection, Fault Proof and Restricted Demand Management

In this paper, we have designed and installed a shock or fault protection system for a single-phase home electrical system using Circuit Breaker (CB) devices available on the market, bearing in mind that certain product areas do not provide shock protection to consumers. Our novel Smart Meter Circuit Breaker (SMCB) is designed to achieve a fail-proof shock protection system architecture that could be incorporated into existing Smart Meters (SM) within a Device Level Load Meter (DLLM). We also illustrate how a colonized and alienated appliance Authentication Outlet (AO) system could be used advantageously for a shock or fault protection system and for our novel Restricted Demand Management system with the help of a distinctive load signature alienated appliance AO. Our Restricted Demand Management system could be used together with the Scheduler Demand Management system already on the market. Finally, this paper shows how our SMCB for an alienated appliance AO detection system for a single-phase home system was simulated, built and tested. The proposed home layout and the Restricted Demand Management System are simple to program and implement and help to reduce energy bills as only particular appliances are allowed to operate at certain times during the day and night. The system also restricts some hazard risk appliances from being used at other outlets. Our proposed system is completely hazard, fault and shockproof for a single phase home electrical system

Juggling an Arduino for multi-utility-meter, load profiling and a novel waveform capture logger applications

It's obvious we love Arduino due to its simplicity but it does not lack in handling complexity. We have put together a list of ideas using Arduino as utility metering. We have included the hardware design, software and wireless topology system used. Our design is capable to preform multi-utility-metering, utility real time load profiling and a novel utility waveform capture logging. In this paper we present off-the-shelf modules that could easily build and be programmed to fulfill utility metering transformation and integration with the existing utility meters. The same hardware can be used as multi-utility-meter, load profiling or waveform capture with just a program flicker. Our utility meter can be used for detecting energy expenditure breakdown per appliance, power hungry faulty appliance and recognition of occupant activity. It also helps empower building owners of energy awareness
