SECTION 4 SWITCHED CAPACITOR VOLTAGE CONVERTERS …
SWITCHED CAPACITOR VOLTAGE 4 SWITCHED CAPACITOR VOLTAGECONVERTERSWalt Kester, Brian Erisman, Gurjit ThandiINTRODUCTIONIn the previous SECTION , we saw how inductors can be used to transfer energy andperform VOLTAGE conversions. This SECTION examines SWITCHED CAPACITOR voltageconverters which accomplish energy transfer and VOLTAGE conversion two most common SWITCHED CAPACITOR VOLTAGE CONVERTERS are the VOLTAGE inverterand the VOLTAGE doubler circuit shown in Figure In the VOLTAGE inverter, thecharge pump CAPACITOR , C1, is charged to the input VOLTAGE during the first half ofthe switching cycle. During the second half of the switching cycle, its VOLTAGE isinverted and applied to CAPACITOR C2 and the load.
converters which accomplish energy transfer and voltage conversion using capacitors. The two most common switched capacitor voltage converters are the voltage inverter and the voltage doubler circuit shown in Figure 4.1. In the voltage inverter, the charge pump capacitor, C1, is charged to the input voltage during the first half of the ...
