The saga begun in video #444 on the basic class-D amplifier continues. In this video, I solve the problem of non-compliance with dead times for driving MOSFETs by adjusting the collector resistors of the PNP transistors upstream of the IR2110 driver. I increase the MOSFET drive gate resistance from 47 ohms to 100 ohms, thus producing a spike-free square waveform. I modify the Arduino source code to generate two push-pull PWM signals output from Arduino pins D5 and D6. I replace the output coil with a 1.5mH coil. This way, I can effectively filter the Arduino's 31,250Hz switching frequency, leaving a rectified and inverted sinusoidal output signal.
