Patent number: 11658579Abstract: A resonant control device and a resonant control method thereof is provided. The resonant control device includes a feedback controller and a processor. The feedback controller receives a reference voltage and an output voltage and use the reference voltage to perform voltage compensation on the output voltage to generate a control parameter. The processor generates pulse modulation signals according to the control parameter and a switching parameter and uses the pulse modulation signals to drive the resonant converter to regulate the output voltage. The pulse modulation signal has the maximum frequency and the minimum frequency. The pulse modulation signals control the frequency according to the control parameter and the switching parameter when the control parameter is larger than or equal to the switching parameter. Otherwise, the pulse modulation signals control the resonant converter to operate for a fixed period within each cycle of the pulse modulation signal.Type: GrantFiled: June 1, 2021Date of Patent: May 23, 2023Assignees: Mean Well (Guangzhou) Electronics Co., Ltd., Mean Well Enterprises Co., Ltd.Inventors: Hsin-Hung Lu, Po Han Huang
