Title:
POWER SUPPLY DEVICE, AND METHOD FOR CONTROLLING POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/002998
Kind Code:
A1
Abstract:
In a power supply device according to the present invention, an input voltage (power supply voltage) value is detected by an input-side voltage detection circuit, and a comparison voltage (error voltage) for comparing with an on timer (timer signal) for determining the on-time of a switch element is subtracted in accordance with said input voltage value. The power supply device is capable of reducing the total harmonic distortion while applying on-time control.
