Right here can be the 200W MOSFET amplifier powered based on four item of IRFP250N, they are very cheap and easy to find in the electronic marketplace in your region. The circuit has long been constructed and examined with very good efficiency.
This 200W MOSFET amplifier circuit developed for one or mono audio channel program. You should construct two very similar circuits for stereo audio software. Construct one 1st for efficiency assessment to make sure that this routine actually wongking well with great audio overall performance.
The energy supply used for this signal is certainly a symmetrical / double polarity type. You require 4 amperes minimum of transformer with +/- 45V output. For stereo system application, use about 8 amperes, although the 5A transformer is certainly good sufficiently 😀.
