Tracing this section allows you to measure the gate waveform directly at the output connector.
Physically, these modules are designed to plug directly onto a stack of IGBTs or be mounted on a heatsink adjacent to the power unit. The reveals how logic-level PWM signals from the main control board are converted into high-current, high-voltage gate pulses capable of switching hundreds of amps.
