US Patent 7729133 Secondary side-driven half-bridge power supply
All edits
The present invention discloses a secondary side-driven half-bridge power supply, which has a half-bridge transformer. A MOSFET unit is connected to the primary side of the half-bridge transformer, and an output rectifier/filter circuit connected to the secondary side of the half-bridge transformer. In the present invention, a PWM controller generates a control signal and sends the signal to a separating element. The control signal is used to drive the MOSFET unit, and the MOSFET unit then drives the half-bridge transformer. The output rectifier/filter circuit processes the signal output by the half-bridge transformer to provide voltages for external loads. The present invention can increase the power efficiency, raise the working frequency, and reduce the cost.
