Abstract

This paper presents a boost converter integrated with a flyback converter with Zero Voltage Switching (ZVS) and active clamp technique. A bidirectional boost converter is integrated with a series output module as Parallel Input Serial losses and cost also get increased and the circuit designing becomes more complex. A coupled-inductor is employed as a favorable step- up technique because of its simple structure [5]-[7]. By using coupled inductor the voltage and current stresses of the Output configuration. The flyback converter with Voltage active switches can be reduced. It can achieve a high Doubler Rectifier (VDR) act as a series output module. This integration makes a bidirectional boost converter an active clamp circuit which is connected to the output side in order toefficiency and protect the switch from the high peak voltage. But the voltage stress on the boost diode is increased and high voltage operation of the diode might induce a high reverse extend the step up ratio. A converter with active clamp recovery problem. Besides, as the auxiliary turns of the technique is used to recycle the leakage energy, to eliminate the voltage spike due to coupled inductors and also to provide a mechanism to achieve ZVS. To overcome the efficiency degradation during light load due to load dependent soft switching of the ZVS, a control method using Pulse Width Modulation (PWM) proportional to the load current is used.
