Active Clamp Forward Converter

In active clamp forward converter topology, the

MP1925 drives the MOSFETs with alternating

signals. The high-side MOSFET, in conjunction

with Creset, is used to reset the power transformer

without loss.

This topology is optimal for running at duty cycles

exceeding 50%. The device may not be able to

run at 100V in this topology (see Figure 6).
