ABSTRACT:
A method of improving efficiency in a boost regulator circuit includes the steps of transferring energy stored in a load to an energy storage component and transferring energy back from the energy storage component to the load. This method may be actuated in a boost regulator circuit having a first energy storage component, means for initiating and discontinuing energy storage in the first energy storage component, a capacitive load, a bi-directional drive circuit coupled to the first energy storage component, a second energy storage component coupled to the drive circuit, and means for transferring energy between the capacitive load and the second energy storage component, wherein when the voltage having a first polarity across the capacitive load reaches a predetermined voltage it transfers the energy in the capacitive load to the second energy storage component and subsequently transfers the energy back to the capacitive load in the second polarity, thereby conserving energy and substantially reducing power consumption of the boost regulator circuit.
