I am using 4 MOSFETs in an H-bridge. The H-bridge is controlled with two MOSFET drivers (specially IR2113). I aim to drive the H-bridge via PWM which is carrying a 50Hz sine wave.
Note that, the load is not a motor. Instead, the H-bridge is being used as a inverter. My question is, does the PWM need to be inverted for one of the drivers? Each driver will handle one side of the H-bridge, so there will be a left-side driver and a right-side driver.
Assuming I feed the left-hand side driver with PWM waveform direct from the microcontroller, should I invert the PWM in order to control the right hand side?
I suppose the question really is, how do I drive an H-bridge, intended for inverter application?
