Technical FAQs 4

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.

What is an active discharge circuit for electric vehicle inverter?

1. An active discharge circuit (10) for electric vehicle inverter (1), the active discharge circuit intended to be connected in parallel with a DC link capacitor (5) connected between positive and negative lines (3,

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.

What is a discharge resistor?

Discharge resistors are used to discharge DC links. They discharge the electricity after an electric vehicle has been switched off and convert the energy into heat. This allows the DC link to be discharged reliably. The requirements and various methods for how best to carry out the discharging process are explained below.
