Do EV traction inverters need a DC link active discharge?Every EV traction inverter requires a DC link active discharge as a safety-critical function. The discharge circuit is required to discharge the energy in the DC link capacitor under the following conditions and requirements: Power transistor on, off control using the TPSI3050-Q1.
How does a DC link discharge a resistor?When discharging the DC link using constant power, intelligent control electronics apply a sequence of constant power pulses to the resistor at a high frequency, typically referred to as PWM. As a result, the discharge energy is distributed evenly over the entire discharge process of the DC link.
Why do EV inverters need to be discharged?Abstract: when an Electrical Vehicle (EV) encounters an accident or the vehicle is taken to a service station, the DC-link capacitor in the inverter must be discharged to ensure safety of both the passengers and the operator.
