Current source for the switchgear thermal test

By Jiří Košíček


This thesis describes the design of semiconductor source for laboratory measurements of switchgears. The proposed source is able to use 16-250Hz frequency, fulfilling the standard value of voltage and current distortion. There are explained the theoretical knowledge of various types of inverters without transformer in the thesis. Furthermore, a circumferential proposal of source is made, which includes calculating the desired properties of individual components, their choice from offers from various manufacturers, and subsequently is constructed the total design solution. It is described the control and management of designed source and it is evaluated for the function finally
