Converting available electrical power to desirable electrical power

Techniques are disclosed for converting available electrical power to desirable electrical power. One embodiment of the techniques calls for a boost circuit to convert low power Win at a terminal TVin to high power Wout at a terminal TVout. The boost circuit includes a voltage generation circuit, a capacitor Cstore, a timing-control generator, and a boost regulator. The voltage generation circuit converts voltage Vin at terminal TVin to voltage Vstore at a terminal TVstore wherein, in one embodiment, Vstore is less than Vin. Further, the current Icharge provided by the voltage generation circuit at terminal TVstore is less than the current Iin at terminal TVin. In one embodiment, capacitor Cstore, being charged by current Icharge, stores necessary charge to provide appropriate currents and voltages to the boost regulator. The timing-control generator uses voltages Vin and Vstore to provide a timing-control signal Tcontrol, which controls the timing operation of the boost regulator. In one embodiment, Tcontrol resets the boost regulator until capacitor Cstore accumulates enough charge to provide appropriate power to the load at terminal Tvout through the boost regulator. The boost regulator, when in operation, converts Vstore to Vout.
