“…So the overlap between this non-zero current and voltage interval will result in unwanted power losses. Therefore, in high-frequency and high-power converters, soft-switching techniques such as zero voltage switching (ZVS) [1][2][3][4][5][6][7] and zero current switching (ZCS) should be applied to reduce switching losses and electromagnetic interference (EMI) noises. In converters with IGBT switches due to tailing current problem at turn off instant, ZCS or zero-voltage zero-current switching (ZVZCS) [8][9][10][11][12][13][14][15][16][17][18][19][20] is more effective and vastly applied.…”

A zero-voltage and zero-current switching full bridge converter with series resonance tank is presented in this study. This converter is based on standard full bridge topology and a series capacitor is added in the primary side to reset the leakage inductance current without any additional auxiliary circuit. Leakage inductance of the transformer is used as the resonance inductance. Using series resonance tank and applying control pulses with fix frequency, zero-voltage switching for leading leg and zero-current switching for lagging leg is achieved. The output power is controlled using phase shift technique. In the proposed converter, soft-switching condition is attained for wide range of load variation. Due to its high performance and minimum additional components with respect to regular converter, this converter can be applied for medium to high-power applications. Topology and operating modes are discussed and the validity of theoretical analysis is verified by prototype experimental results.

“…Phase shift pulse width modulation is mostly applied to drive full bridge (FB) converter in order to achieve ZVS [2,3,[5][6][7] or ZVZCS [9][10][11][12][13][14][15][16][17][18][19][20]. In ZVZCS converters, leading leg switches will operate under ZVS condition and lagging leg will operate under ZCS condition.…”
