Bridge circuit and rectifier including the same

A rectifier, comprising:

• a bridge circuit comprising
• a first leg comprising a first switching device and a second switching device connected between an output node for outputting a rectified voltage and a ground,
• a second leg comprising a third switching device and a fourth switching device connected between the output node and the ground, and
• a first charge recycler connected between a gate of the first switching device and a gate of the third switching device, and configured to transfer charges accumulated in the first switching device to the gate of the third switching device prior to turning on the third switching device;
• and
• a controller configured to control the first switching device, the second switching device, the third switching device, the fourth switching device, and the first charge recycler.

A rectifier, comprising:

• a bridge circuit configured to receive an alternating current (AC) input voltage and output a rectified voltage, and comprising
• a first switching transistor and a fourth switching transistor configured to be turned on or off together based on the AC input voltage,
• a second switching transistor and a third switching transistor configured to be turned on or off together based on the AC input voltage,
• a first charge recycler configured to transfer charges accumulated in the first switching transistor to a gate of the third switching transistor prior to turning on the third switching transistor, and
• a second charge recycler configured to transfer charges accumulated in the second switching transistor to a gate of the fourth switching transistor prior to turning on the fourth switching transistor;
• and
• a controller configured to control the bridge circuit.
