High efficiency LED driver

The technology can solve the problem of insufficient life of the electrolytic capacitor of the conventional power converter and can improve the conversion efficiency by more than 1% to 3%. The technology develops an active two-phase energy converter, which replaces the electrolytic capacitor to absorb the chopping voltage and current caused by the switching frequency, thereby reducing or removing the problem of the electrolytic capacitor required by the conventional converter. The power converter using the present technology can effectively increase the life of the converter due to the electroless capacitor.
