A half-current-multiplier rectifier (HCMR) is proposed, which is capable of increasing the output filter current of phase-shifted full-bridge (PS-FB) by 1.5 times. The HCMR filter is based on an autotransformer structure and improves the valid duty cycle of the PS-FB converter by using the induced current from the common winding. The primary current will decrease rapidly during the dead time period, effectively reducing the transition current level and the transition period. Accordingly, the new valid duty period is almost close to the terminal ${v}_{AB}$ period, over the entire load range, and the power delivery goes nearly in the entire ${v}_{AB}$ period. Experiments have shown that although the zero-voltage switching (ZVS) of all switches can usually implement in continuous-conduction mode (CCM) and most discontinuous-conduction modes (DCMs), it still performs excellently at light loads. Maintenance of 89%–94% high efficiency over a wide load range is like the performance of current-doubler rectifier (CDR) filter.

用于使用基于自耦变压器的滤波器的半电流倍增器整流器的移相全桥转换器

提出了一种半电流倍增整流器(HCMR)，能够将移相全桥(PS-FB)的输出滤波电流提高1.5倍。HCMR 滤波器基于自耦变压器结构，通过使用来自公共绕组的感应电流来提高 PS-FB 转换器的有效占空比。初级电流会在死区时间内迅速下降，有效地降低了过渡电流水平和过渡期。因此，新的有效值班期几乎接近终端 ${v}_{AB}$ 期间，在整个负载范围内，电力输送几乎在整个 ${v}_{AB}$ 时期。实验表明，虽然所有开关的零电压开关 (ZVS) 通常可以在连续导通模式 (CCM) 和大多数非连续导通模式 (DCM) 下实现，但它在轻负载下仍然表现出色。在宽负载范围内保持 89%–94% 的高效率就像倍流整流器 (CDR) 滤波器的性能。
