![]() Unregulated is suitable for audio purposes. If its your first time building a SMPS then I suggest you start with a simple one with no feedback. Efficiency tends to be better with full bridge as less current is needed for the same power due to the primary voltage is double. Having full bridge needs more winding on the trafo and the circuit will be more complicated and more care is needed. Regarding efficiency I got 90% or better in my prototypes.įull bridge is usually used for more power above 1000 watts. The duty cycle is more or less 60% for audio to get to the power needed. I think if you use half bridge is well suited to the power level you want for audio purpose. In theory half bridge is suitable up to 500w but I got 1200 out of a half bridge smps.
