Forward converter ic
WebAn active-clamp circuit can be divided into high-end and low-end components, based on the position of the auxiliary MOSFET. For example, the MP6005 uses a low-end active-clamp circuit. When the primary-side main MOSFET turns off, the switching voltage is composed of the magnetizing inductance’s reset voltage and the clamping capacitor voltage. WebThe forward converter is derived from the buck topology. The main difference between the two topologies is that the transformer employed in the forward topology provides …

Figure 1-1 shows the basic configuration of a boost converter where the switch is integrated in the used IC. Often lower power converters have the diode replaced by a second switch integrated into the converter. If this is
WebIn a flyback converter, this energy is transferred to the secondary side. However, in a forward convert-er, the transformer construction prevents this energy transfer, which necessitates an extra circuit to deliver the energy back to the C1 input capacitor. This extra circuit can be either a reset winding or an active clamp circuit.
