Abstract
The invention discloses a voltage clamping and power recycling circuit in which the disclosed circuit structure can absorb voltage surges caused by lowering loads and still recycle the surge power for greatly raising efficiencies and reliability of the system. The disclosed voltage clamping and power recycling circuit includes a diode, an input capacitor and a power-source converter. The diode and the input capacitor recycle the voltage surges on the load to the power-source converter, which will then make the recycled power fed in the power-supply end to thereby attain the purpose of clamping load voltages and recycling power.
