POWER CONVERSION APPARATUS AND POWER CONVERSION METHOD THEREOF
First Claim
1. A power conversion apparatus comprising:
- a rectifying unit comprising 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,wherein the rectifying unit rectifies the single-phase power by using the pulse signal inputted to a gate terminal of the SCR.

Abstract
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.
