Abstract: A method of operating a bridge switch control circuit is disclosed for controlling at least one pair of complementary switches. First, a first driving signal, a second driving signal, a first latching signal, and a second latching signal are provided. The first driving signal and the second driving signal drive the complementary switches. Afterward, it is to judge whether the first driving signal triggers one of the complementary switches by a rising-edge manner. If YES, the first latching signal is controlled at a high-level status and the second latching signal is simultaneously controlled at a low-level status. Afterward, it is to judge whether the second driving signal triggers the other of the complementary switches by a rising-edge manner. If YES, the second latching signal is controlled at a high-level status and the first latching signal is simultaneously controlled at a low-level status.

Abstract: A power supply includes a transformer winding, a switching circuit, a controller and a filter circuit. The transformer winding is configured to provide a first voltage. The switching circuit is coupled to the transformer winding and includes a first and a second switching unit. On the condition that the power supply is operated under a standby mode, the controller controls the first and the second switching units to provide a discharging path between two terminals of the transformer winding. On the condition that the power supply is operated under an operating mode, the controller controls the switching circuit such that the switching circuit provides a second voltage according to the first voltage. The filter circuit is coupled to the switching circuit and configured to filter the second voltage to provide an output voltage.

Abstract: A three-phase resonant converter includes a three-phase transformer, an input bridge arm assembly, an output bridge arm assembly, and a control unit. The input bridge arm assembly has three input switch arms, and each input switch arm has an upper switch and a lower switch. The output bridge arm assembly has three output synchronous rectification switch arms respectively coupled to the three secondary-side windings. Each output synchronous rectification switch arm has an upper rectification switch and a lower rectification switch. The control of each output synchronous rectification switch arm is corresponding to the control of each input switch arm. The control unit controls the upper rectification switch or the lower rectification switch to be turned on with a leading phase angle to the corresponding upper switch or the lower switch so as to maintain an output voltage of the resonant converter to be higher than a voltage threshold.
