150 Watt Amplifier Circuit

100W Subwoofer Amplifier Circuit Diagram MOSFET

Circuit Description: MOSFET power amplifier circuit based on IRFP240 and IRFP9240 MOSFETs is shown here. The amplifier operates from a +45/-45 V DC dual supply and can deliver 100 watt rms into an 8 ohm speaker and 160 watt rms into a 4 ohm speaker. This Subwoofer Amplifier Circuit Diagram is suitable for a lot applications like general purpose amplifier, guitar amplifier, keyboard amplifier. The amplifier can be also used as a sub woofer amplifier but a subwoofer filter stage has to be added before the input stage. The amplifier has a low distortion of 0.1%, a damping factor greater than 200, input sensitivity of 1.2V and the bandwidth is from 4Hz to 4 KHz. Circuit Features: Assemble the circuit on a good quality PCB. Use a +45/-45 V DC, 3A dual supply for powering the circuit. Power supply voltage must not exceed +55/-55 V DC. Before connecting the speaker, check the zero signal output voltage of the amplifier and in any case it should not be higher than 50mV. If it is h

400W Subwoofer amplifier circuit

Features Class-T architecture with proprietary DPP “Audiophile” Sound Quality Full Audio Bandwidth, 20Hz to 20kHz High Efficiency Supports wide range of output power levels and output loads by changing supply voltage and external Mosfets Compatible with unregulated power supplies Output over-current protection Over- and under-voltage protection Over-temperature protection 48-Pin LQFP Package Description The TDA1400 is a one-channel, Amplifier Driver that uses Tripath’s proprietary Digital Power Processing (DPPTM) technology. The TDA1400 offers higher integration over previous Tripath amplifiers driver chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. The TDA1400 is typically configured as a single supply, bridged output. This makes the power supply requirements simpler and maximizes the output power for a giv

Subwoofer Amplifier Circuit 400W MOSFET

Subwoofer Amplifier Circuit 400W MOSFET Power amp 400W IRFP448 Circuit Amplifier circuit today,We would like to show you for the MOSFET 400 watt amplifier is amplifier on my kW shares the same circuit and basic PCB layout. The only real difference is the number of output devices to the device. We have using The IRFP448 design while the MOSFET amplifier 14 O / P devices. These amplifiers can be used for virtually any application that requires high performance, low use Noise, distortion and excellent sound quality. Examples would be subwoofer amplifier should FOH stage Amplifiers, surround a canal a very powerful sound amplifier, etc. The 400W MOSFET-amplifier has four key stages of amplification. We are looking to start any Phase appropriate detail. The bias and buffer stage As the name suggests All Q ,C and ZD the Bias and buffer phases. Its main goal is to provide a stable MOSFET Gates and offset voltage and the voltage buffer amplifier stage of the High Resource capac
