After verifying the space vector generation and PWM modules, the 3-phase inverter hardware can be tested by looking at inverter outputs U, V, and W on a scope. This can be compared against the PWM pulses (PWM-1H to 3H) fed into the inverter. It is advisable to gradually increase the DC bus voltage during this test. Check inverter outputs U, V, and W using an oscilloscope with respect to the inverter GND, while taking care of scope isolation requirements. This ensures that the inverter is working properly.
