Abstract
A method and apparatus to perform resonant recharge transfers energy from an AC power source (e.g., a power line) or from a DC power source or from bulk capacitors to a deactivation capacitor. The resonant recharge occurs faster than conventional techniques without the need for dissipative current limiting control elements. Through the employment of a resonant approach, the natural impedance of the resonant circuit limits the current without high resistive losses of a limiting resistor or other current limiting regulator. This may increase the efficiency of the recharge circuit and may charge the deactivation capacitor to a voltage that is higher than the voltage of the power source.
