Design a feedback loop compensator for a flyback converter in four steps

Due to their versatility, ease of design, and low cost, flyback converters have become one of the most widely used topologies in power electronics. Its structure derives from one of the three basic topologies—specifically, buck-boost topology. However, unlike buck-boost converters, flyback topologies allow the voltage output to be electrically isolated from the input power supply….

Power Tips #138: 3 ways to close the control loop for totem-pole bridgeless PFC

Introduction Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current control loop of a continuous conduction mode (CCM) totem-pole bridgeless PFC is not as straightforward as it is for a traditional PFC. A traditional PFC operating…
