200W Audio Amplifier with Mosfet BUZ905P-BUZ900P This project is develop from the MOSFET Power amplifier 100W that posted which it take to use in many activity such as Guitar amp,Mic,or Home theater and you will be to apply it. As many people prefer because of its robustness MOSFET legendary. Altronics had a MOSFET amplifier with 200W, the product in a 4Ω, and we have decided to take a look at is. It turns out that on the basis of the Pro One “, as described above, even if this version of Altronics and to the various MOSFETs. He has a rated output of 140W to 200W into 4Ω and 8W. Frequency range of 1 dB 20Hz up to 80kHz (Fig. 1). THD is less than 0.1% at full power (Fig. 2) and signal to noise ratio when compared to 200W is better than -100 dB unweighted. Performance of the prototype Output power (RMS ):… 140W into 8 ohms, 200W into 4 ohms Frequency Response:. 20Hz – 80kHz-1dB points (see Figure 1) Input sensitivity: ………… 830mV for 200W into 4 ohms Distortion: … <0.1% (20 Hz –...
