摘要： A hybrid power conversion circuit includes a high-side switch, a low-side switch, a transformer, a resonance tank, a first switch, a second switch, a first synchronous rectification switch, a second synchronous rectification switch, and a third switch. The resonance tank has an external inductor, an external capacitance, and an internal inductor. The first switch is connected to the external inductor. The second switch and a first capacitance form a series-connected path, and is connected to the external capacitance. The first and second synchronous rectification switches are respectively coupled to a first winding and a second winding. The third switch is connected to the second synchronous rectification switch. When an output voltage is less than a voltage interval, the hybrid power conversion circuit operates in a hybrid flyback conversion mode, and otherwise the hybrid power conversion circuit operates in a resonance conversion mode.

摘要： An active bridge rectifying control apparatus includes a bridge rectifying unit and a rectifying control module. The rectifying control module includes a phase control unit, a low-side drive unit, and a self-drive unit. The phase control unit provides a live line signal and a ground line signal according to a positive half cycle and a negative half cycle of an AC power source. The low-side drive unit provides a low-side control signal according to the live line signal and the ground line signal. The self-drive unit establishes a drive voltage according to the positive half cycle and the negative half cycle of the AC power source, and provides a high-side control signal according to the low-side control signal. The bridge rectifying unit rectifies the AC power source into a DC power source according to the low-side control signal, the high-side control signal, and the drive voltage.
