ZCS怎么读

A ZCS push pull forward converter using resonant elements is proposed.

提出了正激推挽电路的ZCS方案。

At present, the research of the single-stage power factor correction ( PFC) circuits is mostly concentrated on the application of low powers. A zero-current-switching ( ZCS) single-stage AC/ DC converter with high power factor is proposed to use in medium and high power conditions.

目前，对单级功率因素校正电路的研究大多集中在小功率应用领域，为此该文提出一种能够应用于中大功率场合、实现了零电流开关的单级高功率因数AC/DC变换器拓扑。

The decreasing time of free-wheeling current is relative to duty cycle in the exiting FB-ZVZCS-PWM soft-switching inverter arc welding power supply with the block capacitor, and it is hard to achieve zero current switching ( ZCS) for lagging leg with low duty cycle.

现有FB-ZVZCS-PWM软开关弧焊逆变电源采用阻断电容衰减原边环流电流所需的时间与占空比有关，占空比很小（电源输出电压很低）时滞后臂难以实现零电流开关。
