Traditional DC-DC Boost converters are used in high voltage applications, but they are not economical due to limited output voltage, large voltage ripples, current ripples and power losses. A closed loop control scheme for a simple DC-DC Boost converter in designed and the performance characteristics are studied using MATLAB simulink. The performance of the controller is also studied for variou...

A compact dc/ac inverter for automotive is presented and experimented. The proposed inverter consists of fall bridge inverter and a new ZVCS quasi-resonant push pull dc/dc converter. The new dc/dc converter converts input 12 V (from battery) to high voltage (about) 200V at very high conversion efficiency without regulation. The high voltage will be converted to ac at the desired voltage and fre...
