Bidirectional DC-DC Converter Using Zero Voltage Switching

DC-DC Converters are used for storage of energy from renewable energy resources. These converters uses zero voltage switching concept to reduce the losses. In order to increase the operating range of the converter duty ratio is varied using effective control technique. By changing the duty ratio with transformer in the output, zero switching losses can be obtained over the full range of duty cycle by the voltage second balancing. Analysis of two port and three port converters is done and simulated to verify the analysis.
