ABSTRACT:
A linear voltage regulator which includes on its input side an array of switched super capacitors coupled between the power source and the load. This apparatus is capable of delivering currents typically from milliamperes to greater than several amperes at very low switching frequencies. In addition by using capacitors rather than resistors or transistor devices to drop voltage on the input side, power consumption is reduced. The array of capacitors is switched by simple analog circuitry or a switching logic with or without a processor subsystem and the capacitors themselves are of the super capacitor type, thus providing very high capacitance, and are effectively series connected during certain phases of operation with the input terminal of the conventional linear voltage regulator portion of the apparatus. Energy stored in the super capacitors during the various phases of operation is reused.
