Control of Output Voltage of Simple DC-DC Converters

This paper proposes a new simple and fast control strategy for a dc-dc converter. This strategy is able to create any desired voltage waveform at the output. Switching signals are generated using hysteresis band control. In this strategy output voltage compares with reference voltage waveform for getting switching pattern. Because of low number of switches in power circuit, switching losses is very low. Another application of this circuit is speed control of dc motors by changing the dc 1 voltage magnitude. Energy recovery is one of the best characteristics of this circuit
