A New High Efficiency High Step Up Converter with Coupled Inductor and Switched Capacitor
Incremental converters are nowadays widely used in new energy systems because new energy systems such as photovoltaic, fuel cell, etc have low output voltage and need to be increased to the desired level to connect these systems to the global electricity grid; DC-DC converter converters have played a prominent role, but these converters have to incur significant losses to the system and, on the other hand, operate under the input-to-output variations, so the switchers were considered soft switches. In this study, a non-isolated booster converter with soft switching voltage gain-raising technique was designed. This converter has a switch that is controlled by the Pwm signal. The benefits of this converter include reduced switching losses, simplicity of operation, provision of soft switching and low voltage stress; an active clamp is used to provide soft switching for multiple voltage elements and back cells to maximize gain and input. The converter used an auxiliary branch to increase the gain instead of using the output inductor at the input, and in addition an inductor was used as a filter inductor to reduce the input ripple. This converter has six states. The switches are switched on under zvzcs and switched off under zvc conditions.
