This inverter circuit is very useful for low load application such as emergency light, radio, or DVD player. With transistors as main active component, please take more attention when you assemble this 100 W inverter circuit. Power source of this circuit just 12V DC, but can produce about 100W at 220V AC with simple assembling [...]

Using IC 4001, 4027, NE555, and CA3130, this circuit can convert 24VDC to 220VAC 300W. A pairs of MJ15003 or 2N3773 as the last active components before drive the pulse into the transformator.

Basic operation of this circuit is similar DC to DC converter. With input from 18VAC at 800mA then converted to DC by B1 bridge rectifier. R11 work as adjuster, a twin of IRF510 as final amplifier, and a CT transformer is the last converter to provide the high voltage output.

For large source supply at your amplifier or another application, this DC-DC converter is recommended. This circuit already tested, and no problem when connected the load.

A simple step up DC to DC converter with a maximum draw of about 800mA. Applying a op-amp as a square wave oscillator to trig an inductor and another op-amp in a feedback loop, provides a 24V power source for many uses.

High-performance amplifier. Ultra low distortion but high voltage DC while operated. Using two on-board 6.5A fuses, just cause this circuit is capable of delivering around 300W of music power into 4Ω, each fuse carries around 4.4A RMS or higher.

This is a small and simple audio amplifier with TDA7294. Using 2 TDA7294 for stereo (2×80 watt) mode and bridge mode (180 watt). The TDA7294 for use as class AB audio amplifier.

This 400 W MOSFET Audio Amplifier using IRFP448 circuit is simple project. With low noise and distortion, but powerful. As the fuel, this project consume 70-80 Vdc and 5 A fuse as the protector for short circuit.

Power amplifier settled on HEXFET IRF9540 and IRF540 which probably produce 65 W at the output. This circuit is simple and have a good audio quality. For thermal static, use heatsink on Q8, Q10, Q11, Q12, and Q13.

This circuit possible to deliver about 200W power output produce by Phillips Semiconductor. Using 2 PHP1BN11QT, input voltage between 30 and 45 VoltsDC for this circuit, trigger the 4Ω impedance load speaker in to a powerful audio output. Other features of this circuit are THD+N (total harmonic distortion-plus-noise) PL = 10 W frequency range from [...]

Very high power amplifier with 10 pairs of power transistor. Can use MJ15024 and MJ15025 or MJ21193 and MJ21194. Those 20 pieces transistor work as final active component for final gain. This circuit required dual output power supply 130V.

Can be a standalone or teamed with Pre-Amp, this circuit show us a high-class headphone amplifier. With low distortion and noise, its seat drive low or high impedance to max power levels. Need only a power supply and a volume control pot for apply among any line-level signal source, and featured dual output.
