Abstract
In this Paper, a new nonisolated single switch DC-DC converter with high voltage gain is proposed. The proposed converter introduced a hybrid switched capacitor technique for providing high voltage gain without high switch duty cycle. Also an auxiliary circuit has been applied to the proposed converter for providing soft switching condition. This circuit consists of two coupled inductor and one diode. Therefore converter switch is turned on under ZCS condition. The other advantages of the proposed converter are continuous input/output current, simple structure and PWM control. The principle of operation in continuous conduction mode (CCM) is analyzed. The proposed converter is simulated by PSPICE for confirming the results of theoretical analysis.
