High power factor AC-DC converter with reactive shunt regulation
First Claim
1. A high power factor AC to DC converter with shunt regulation comprising first and second power converter means for converting AC power to DC power, said first power converter means for receiving and regulating an input power from a power source and delivering at least a component of an output power of said AC to DC converter means to a load, said second power converter means delivering another component of said output power to said load, wherein said first power converter means comprises a unidirectional power output operatively connected to said load and said second power converter means comprises a bi-directional power input operatively shunted across said load and further comprises a bi-directional power output operatively connected to an energy storage means for storing a difference between said input power and said output power components whereby said second power converter means regulates the sum of output power to said load.

Abstract
A high power factor AC to DC converter with shunt regulation include first and second power converters for converting AC power to DC power; the first power converter receives and regulates input power from a power source and delivers a component of an output power to a load. The second power converter delivers another component of the output power to the load. The first power converter includes a unidirectional power output connected to the load. The second power converter includes a bi-directional power input shunted across the load with a bi-directional power output connected to an energy storage apparatus for storing a difference between the input power and the output power components
