Pemanfaatan Harmonisa Pada Beban Non Linier Sebagai Sumber Energi Menggunakan Full Bridge DC-DC Converter Dan Inverter

ABSTRACT The use of non linear loads such as VSD cause a large harmonics. Because of the harmonic actually need to reduction the spectrum of harmonic by installation of passive filters. Power on the filter inductor can be utilized as a source of energy by replacing the inductor into the transformer. Rectified secondary side and raised using a full bridge DC-DC converter is then converted using an inverter in the hope of a new alternative energy sources. Utilization is limited by the power from filter transformers only, so do not pay attention the harmonic currents. Full bridge DC-DC converter using phase-shifted method on its DC voltage regulation. While the inverter using the Sinusoidal Pulse Width Modulation (SPWM) method. In planning consists of a battery 36 V, full bridge DC-DC converter as step up DC voltage into 300V, inverter changes 300V DC voltage into 220V AC, and the microcontroller ATmega16 as a pulse generator PWM and SPWM. In testing the entire system, with load variation (170 watts) is capable of producing 200 volts AC voltage with a current 0.7 A. Then, after integration with the filter transformer, resulting voltage is 150 volts AC with a load of 18.4 watts. And THDi system changed from 85.3% to 52.89%. When the load is increased to 300 watts, the inverter output voltage drop. Thus the design of full bridge DC-DC converter is less able to meet the planning of power 450 VA.

RANCANG BANGUN MODUL PRAKTIKUM ELEKTRONIKA DAYA (BUCK CONVERTER - BOOST CONVERTER)

Electronic switch-mode DC to DC converters or also known as DC Chopper is mainly used to provide the varies DC output voltage magnitude according to demand of the load. Power input from DC-DC process is derived from the DC power source which typically has a fixed input voltage. Basically, to produce a DC output voltage which achieved, able to do by setting the length of linkage time between the output and input on the same circuit. Components used to perform a liaison function none other is the switches (solid state electronic switches) such as thyristor, MOSFET, IGBT, GTO. Generally there are two functions of DC Chopper operation that is reducee voltage (Boost Converter) from 39 Volt to 15 Volt , and increase voltage (Buck- Converter) 10 Volt to 25 Volt. In this last project we used a PI controller to obtain good output (constant) of a series of DC - DC converter. But, there are still happen any fault om method deciding parameters of KP and KI. So, causing deformity as 6.4% on buck converter�s output within 15 Volt as setpoint, and 28% on boost converter within 25 as setpoint at maximum load.

Backup power supply system as an alternative voltage source supply for household expenses at this project is designed to be able to maintain a constant output voltage according to the rating of 220V, when the load changed or input voltage (from accu) decreased. This backup power supply system consisting of battery 24 V, boost converter increase DC voltage to 100V, the inverter changes DC voltage 100V into AC voltage 70V , 70V to 220V step up transformer and ATmega16 microcontroller as PWM generator for boost and inverter and as proportional control intregal ( PI). PI control the ignition IGBT boost converter to regulate output voltage of the system. From the system test, has been designed, the output voltage of the system is only able to 130V, it is because a large drop that occurred on the side of the transformer. So taken with the 125V setpoint value of the controller parameters Kp = 0.5 and Ki = 0015 at the maximum load 100W/220V Keywords: backup power supply, Boost Converters, Inverters multipulsa, Transformers Step Up, Controls P

RANCANG BANGUN CHARGER BATERAI DENGAN BUCKBOOST KONVERTER

Battery is one of the media for power supplies in electronic devices. However, the battery�s ability supplied power limited on how big the capacity that is stored in batteries. When the battery charge runs out, it needs re-charging (charge), where the device to recharge the battery charge must consider several aspects such as charging current, battery voltage and when the charging process must be stopped, this is considering that batteries for electric bicycles 3x12V/12 ah has a maximum current limit charging 3 A, and with charger in the sales package, not allowed to charge more than five hours. The fact is, many owners of electric bicycles do excessive charging so the battery does not last long. The solution to this problem is to use battery charger, which can be used to charge the battery charge to some voltage rating (12V and 24 V). This battery charger is equipped with buckboost converter for voltage and charging current regulator which way this works is based on the large PWM duty cycle generated by the microcontrolle
