I also post a car amplifier, 100% own achievement. The amplifier consists of SMPS (switching source), SG3525 oscillator and 4 + 4 N-mos IRFZ48 and the amplifier is according to the “classic” N-mos 350 scheme with 6 IRFP240 endpoints. The transformer for SMPS is made of two smaller transformers recovered from an inverter, of which…
