Abstract
A circuit comprising a primary section and a multiple voltage secondary section. The multiple voltage secondary section includes a multiple voltage resonance section, a filter section, and a load coupling section. The circuit also includes a transformer, which is operatively configured to couple the primary and secondary sections. The multiple voltage resonance section includes a capacitance, i.e., an Alexander Topology. This capacitance, which is preferable based on series capacitors, operatively generates a predetermined voltage, such that a turns ratio of the transformer is lower than a non-multiple voltage resonance section to generate the predetermined voltage. Hence, this configuration decreases energy loss from the transformer, thereby increasing efficiency.
