The TL431 is a reference voltage source that is commonly used in the control circuit of isolated power supplies. In this example, the design of a TL431-based type 2 voltage controller for a flyback converter is presented.
Active power factor correction (PFC) is used extensively in AC-DC converters since it allows the converter to meet harmonic standards without the need for a bulky and costly input filter that normally accompanies a passive AC-DC converter. In this application example, a single phase boost-type 600 W PFC converter is modeled in PLECS.
Space vector control is a popular technique used in the control of motor drives or three-phase rectifiers since it offers reduced switching losses and better utilization of the DC bus compared to conventional PWM control. This PLECS demo model demonstrates space vector control of a three-phase boost-type rectifier.
This PLECS demo model shows a DC-DC flyback converter operating in discontinuous conduction mode with two outputs. The model combines the electrical power circuit with a special magnetic circuit for the flyback transformer and the discrete controller.
This PLECS demo model shows a 300 W switched-mode power supply with power factor correction. The simulation combines the electrical power circuit, the control system with a standard IC and the thermal behavior of the semiconductors.
