Here can be the 200W MOSFET amplifier powered based on four piece of IRFP250N, they are very cheap and simple to find in the digital market in your area. The circuit has become assembled and tested with very good overall performance.
Power MOSFET IRFP250, SiHFP250 Vishay Siliconix FEATURES. Dynamic dV/dt Rating. Repetitive Avalanche Rated. Isolated Central Mounting Hole.Fas St wcthniig. Ease of Paralleling. Simple Drive Requirements. Compliant to RoHS Directive 2002/95/EC DESCRIPTION Third generation Power MOSFETs from Vishay provide the.
This 200W MOSFET amp circuit created for individual or mono audio sales channel program. You should construct two identical circuits for stereo audio program. Build one initial for overall performance tests to ensure that this outlet really wongking well with excellent audio overall performance.
The power supply used for this circuit is definitely a symmetrical / double polarity type. You need 4 amperes minimal of transformer with +/- 45V output. For stereo system application, make use of about 8 amperes, although the 5A transformer is certainly good sufficiently 😀. You may make use of the energy supply signal style on this write-up: 200W Strength Amplifier using Transistór
