Abstract
Various voltage multipliers are disclosed for charging high voltage batteries and/or devices. The voltage multiplier includes an input node configured to receive an input voltage; an output node configured to output an output voltage, where the output voltage is greater than the input voltage. In some examples, an apparatus for the voltage multiplier is integrated with a soft switch device to receive antiphase pulsed inputs through a plurality of stages comprising MOSFETs, diodes, and/or full bridge rectifiers.
Claims1
An apparatus for a capacitively coupled multiplier (CCM), the apparatus comprising:
- a positive voltage supply and a negative voltage supply;
- a series of plurality of full bridge rectifier stages connected, on either end of the series, to the positive voltage supply and the negative voltage supply, respectively;
- and
- a capacitor that is connected, on either end of the capacitor, to the positive voltage supply and the negative supply, respectively, wherein the capacitor is parallel to the series of the plurality of full bridge rectifier stages;
- wherein each full bridge rectifier stage comprises a full bridge rectifier and a respective pair of capacitors, wherein the respective pair of capacitors are located on a pair of lines that run in parallel to the full bridge rectifier;
- wherein, for each full bridge rectifier stage, the full bridge rectifier is coupled, at diametric ends of the full bridge rectifier, to the pair of lines;
- and
- wherein one end of the pair of lines comprises a pair of antiphase pulsed input ports configured to receive antiphase pulsed inputs.
