源回路の出力はバッテリー電圧と商用トランスのレキ。Conventionally, uninterruptible power supply circuits have been difficult to limit the load to which they are connected, resulting in excessive quality such as the output voltage waveform being a sine wave, its distortion rate, and output voltage accuracy. The present invention generally adopts a high frequency switching method when the load is a capacitor input type rectifier.
Noting that the AC input voltage range has a considerable margin, we simplified the uninterruptible power supply circuit, and the output of the uninterruptible power supply circuit is equal to the battery voltage and commercial transformer.
