Module 3.0 Introduction to Switched Mode Power Supplies.
www.learnabout-electronics.orgIntroduction to Switched Mode Power Supplies. SMPS circuits are considerably more complex than the linear stabilised power supplies described in Power Supplies Module 2. The main advantage of this added complexity is that switched mode operation gives stabilised designs that can deliver more power for a given size, cost and weight of power unit.
SECTION 4 SWITCHED CAPACITOR VOLTAGE CONVERTERS …
www.analog.comSwitched capacitor inverters are low cost and compact and are capable of achieving efficiencies greater than 90%. Obviously, the current output is limited by the size of the capacitors and the current carrying capacity of the switches. Typical IC switched capacitor inverters have maximum output currents of about 150mA maximum.
