Abstract: (1725 Views)
In this paper, a new Countinous Current Mode (CCM) nonisolated DC-DC interleaved converter is proposed that uses an auxiliary circuit to create soft switching conditions. The auxiliary circuit used in this converter has no switch and provides soft switching conditions for all switching elements from only one resonance path. Also, the designed auxiliary circuit is not located in the power transmission path from input to output. Due to the use of interleaved structure, the current stress on the switches in the proposed converter is low. This converter has a very simple structure and operation compared to similar structures. The converter control method is also simple and pulse width modulation (PWM) is used to command the switch. Due to soft switching technique, the switching frequency of the converter has increased, this way leads reduced the size and overall volume of the converter, especially the passive elements in the structure, switching and conduction losses and also increased the efficiency of the converter compared to similar structures. Also, the proposed converter with 48V input voltage, 155V output voltage with 100 kHz switching frequency at 900 watts was simulated in PSPICE software. The results of simulation and theoretical and computational analysis confirm the performance of the converter.
