3000w 3kw class d power amplifier project using ic ir2110 cd4049 hef4049 hcf4049 ne555 lm311 and op amp comparator tl071 as the main stage amplifier the driver stage using bd140 bd139 or you can use any driver stage power amplifier transistors. A typical class d power amplifier consists of a sawtooth waveform generator comparator based on an opamp switching circuit and a low pass filter. The combination of the lm4651 driver ic and the lm4652 power mosfet class d power amplifier ic provides a high efficiency amplifier solution suitable for self powered speakers subwoofers and quality car boosters.
This power amplifier can generate great power if given enough power supply.
Louis music inc the information contained on this drawing is proprietary to description chgd by and 10 megohm digital voltmeter. With lm4651 lm4652. Below you can see the block diagram of a basic pwm class d amplifier just like the one that we are building. This basically means that the input is encoded into the duty cycle of the rectangular pulses.
