Latest Patents

Wang is credited with 1 patent: “Switching Converter with Zero-Voltage Switching and Control Method Thereof.” The invention describes a method for controlling a converter that uses a main switch and a synchronous switch to convert an alternating-current input into an output voltage.

The method determines whether the converter operates in discontinuous conduction mode (DCM) or critical conduction mode (CRM). In CRM, it turns off the synchronous switch after a specified period beginning when the inductor current falls to zero. It then turns on the main switch at a voltage valley and turns it off when its on-time reaches a second period related to the first. These steps coordinate switching behavior to support zero-voltage switching.
