    • An apparatus/method is provided. The power conversion apparatus includes: a rectifying unit including a silicon-controlled rectifier thyristor (SCR) for rectifying single-phase power externally inputted; a power factor correcting unit configured to correct a power factor of the power rectified by the rectifying unit; and a control signal generating unit configured to detect a zero-crossing point based on the single-phase power inputted and generate a pulse single of which a width increases as time elapses based on the detected zero-crossing point. The rectifying unit rectifies the single-phase power by using the pulse signal inputted to a gate terminal of the SCR.
    • 提供了一种设备/方法。 该功率转换设备包括:整流单元,其包括用于对从外部输入的单相电力进行整流的可控硅整流器晶闸管(SCR) 功率因数校正单元,被配置为校正由整流单元整流的功率的功率因数; 以及控制信号生成单元,被配置为基于输入的单相电力来检测过零点,并基于检测到的过零点生成宽度随着时间流逝而增加的脉冲单元。 整流单元通过使用输入到SCR的栅极端子的脉冲信号来整流单相电力。
