A New Soft Switching PWM DC-DC Converter with Auxiliary Circuit and Centre-Tapped Transformer Rectifier

New active snubber cell for high power isolated PWM DC–DC converters

“…In above equations, t f main and t f aux are fall time of the main and auxiliary switches, respectively, and durations 3 , 5 , 6 , 7 are given in (13), (17), (19), and (23), respectively.…”

“…(c) There should be no additional current stress on the switches or it should be reduced as much as possible. In the literature, there are various soft switching isolated PWM DC-DC converter or inverter designs [6,[8][9][10][11][12][13][14][15][16][17][18][19][20]. However, most of them lack at least one of the features mentioned above.…”

“…In the literature, there are various soft switching isolated PWM DC–DC converter or inverter designs [6, 8–20]. However, most of them lack at least one of the features mentioned above.…”

“…In [15, 16, 18], the resonant inductor current is higher than the nominal current and the auxiliary switch has additional current stress. In [19, 20], the rate of change of the main switch voltage cannot be slowed down during turn‐on and parasitic capacitor energy of the main switches cannot be recovered.…”

Research on Efficient Soft Switching Based on MPPT of PV Power Generation System

“…The third section introduces the topological structure of basic and improved soft switching. Simulation and Eexperimental Aanalysis is based on Multisim to build a DC-DC BOOST circuit (Mirzaei and Rezvanyvardom, 2020;Faraji et al, 2019;Charin et al, 2013;Pahlavandust and Yazdani, 2020;Öztürk et al, 2018). First, IRFZ24N, a power switch tube suitable for a high-frequency circuit environment and a Schottky diode MBR7545 with a moderate forward voltage drop and a large reverse voltage value are selected from Multisim, and the duty ratio in the circuit is analyzed according to the maximum power point (MPP) of the PV module.…”
