Design improvements for Primary-Side-Regulated high-power flyback converters in Continuous-Conduction-Mode

Primary-Side-Regulation (PSR) indirectly senses output voltage, to eliminate the secondary-side error amplifier and feedback opto-coupler - saving cost and standby power. PSR is commonly used in low-power Discontinuous-Conduction-Mode (DCM) flyback converters, but rarely at high power, or in Continu... View More
