A Voltage Multiplier Based DC-DC Converter with Reduced Switch Stress and Ultra-High Voltage Gain

A novel interleaved non-isolated high-gain topology is presented in this article. This converter reaches its significant gain by combining two voltage multiplier cells (VMCs), a built-in transformer (BIT) with two windings, and coupled inductors (CIs) with two windings. Leakage inductance energy recovery, reduction of input current ripple, flow sharing by interleaved technique, increased flexibility in design by improving the conversion ratio of built-in transformer and coupled inductance, power masts turned on under zero current switching (ZCS), also switched off for Diodes are features of this topology. A voltage of ۲۰V was applied to the simulated topology. As a result, a load output voltage of ۵۳۳V was achieved, and an output power of ۳۲۰ watts was generated.
