Active Power Factor Correction Active power-factor correction can achieve very high power factors—0.98 and above—with reasonably sized components, though the energy efficiency may be slightly lower ...

The primary purpose of using ZVS is to reduce the power loss or power dissipation in the PWM switch during turn-on. More losses occur in the external MOSFET with the increase in switching frequency.

The flyback circuit consists of UC3525A PWM controller, driver, power MOSFET, and transformer. The transformer’s plus and minus outputs combine to provide the output voltage. The UC3525A has two ...

One in the quest for improved energy efficiency and power quality is the use of active harmonic filter power factor correction (PFC) in switched-mode Jon Mark Hancock, Senior Applications Engineer ...
