Figure 5. Topology of IBCC with flyback-type active-clamp circuit. Figure 6. Topology of IBCC with boost-type active-clamp circuit.
Web13 15 OUTA Drive output for the main flyback power MOSFET or IGBT. OUTA has a source resistance of 13 (typical) and a sink resistance of 8 (typical). 14 16 OUTB Secondary output of the PWM Controller. It can be used to drive synchronous rectifier, and active clamp switch, or both. OUTB has source and sink resistances of 22 (typical) and 11 WebThe flyback converter is an isolated power converter. The two prevailing control schemes are voltage mode control and current mode control. In the majority of cases current mode control needs to be dominant for stability during operation. Both modes require a signal related to the output voltage.
WebThis paper proposes an AC/DC single-stage structure by integrating a boost topology and an active clamp flyback (ACF) circuit with power-factor-correction (PFC) function. The PFC function can be achieved by controlling a boost PFC topology operated in the discontinuous conduction mode. With the coordination of active clamping components, a resonant …
