Abstract

A power converter circuit may include a primary (EP) and a secondary (ES) stage. The primary stage may include a first primary winding (Tr1-P) connected in parallel with a first conversion stage (CPP1), and a second primary winding (Tr2-P) similarly connected with a second conversion stage (CPP2). Each of the first and second conversion stages may include a first primary switch (T1, T3) and first auxiliary switching circuit (CAC1, CAC3), and a second primary switch (T2, T4) and second auxiliary switching circuit (CAC2, CAC4). For each conversion stage, the first auxiliary switching circuit and the second auxiliary switching circuit may include a storage circuit (SC1, SC2, SC3, SC4) having a snubber capacitor (Cs1, Cs2, Cs3, Cs4) and diode (Ds1, Ds2. Ds3. Ds4), and a recirculation circuit (RC1, RC2, RC3, RC4) having a recirculation inductor (Lr1, Lr2, Lr3, Lr4), diode (Dr1, Dr2, Dr3, Dr4), and switch (T5, T6, T7,T8). The storage circuit (SC1, SC3) of the first auxiliary switching circuit (CAC1, CAC3) may be connected in parallel with the first primary switch (T1, T3), and the storage circuit (SC2, SC4) of the second auxiliary switching circuit (CAC2, CAC4) may be similarly connected with the second primary switch (T2, T4).
