Transformer stores energy → higher peak voltages and currents.
Efficiency and EMI get challenging above ~100 W.
Large, bulky transformer for ~200 W (24 V×8 A).
Forward Converter
Pros
Better for medium-power (100–300 W): lower peak stresses on the switch.
Higher efficiency and tighter voltage regulation.
Smaller transformer for same power level.
Cons
More complex: needs an output inductor, reset winding or clamping network, and extra diodes.
Slightly more components and gate-drive complexity.
Recommendation:
For a 24 V @ 8 A (~200 W) isolated design, a forward topology (single-forward, push-pull, or half-bridge) is generally preferred for efficiency, transformer size, and EMI control.
Would you like to proceed with a forward-converter schematic block diagram and key component selection?
Here’s a basic forward-converter block diagram to get us started:

This shows the flow from 220 VAC in all the way through isolated forward conversion, output regulation, and feedback. Let me know if you’d like to dive into component choices (transformer turns ratio, controller IC, snubber, output inductor, etc.).
