SYSTEM AND METHOD FOR CONTROLLING QUASI-RESONANT INVERTER AND ELECTRIC HEATING DEVICE EMPLOYING THE SAME |
摘要 |
A quasi-resonant inverter control system includes a mains zero-crossing detection circuit and a controller. The mains zero-crossing detection circuit is operable to detect a plurality of zero-crossing points of an input alternating-current voltage and output a zero-crossing detection signal based on the zero-crossing points. The controller is operable to control a plurality of burst mode period and receives the zero-crossing detection signal. Each of the burst mode periods includes a working duration and a non-working duration. Each of the working durations includes a start point and an end point. The controller is operable to determine the start points and the end points of the working durations based on the zero-crossing detection signal and outputs a control signal based on the start points and the end points of the working durations. An electric heating device and a method for controlling the quasi-resonant inverter are also disclosed herein.
