FAQs 6
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 a DC input in a solar inverter?
The DC input is the power input for solar panels or batteries. Poor quality terminals or improper surge protection can cause power fluctuations or even system failure. It consists of the following two parts: Fuse: The fuse automatically opens if the current is too high, protecting the inverter from damage.
How does a TI power module discharge through a power module?
Discharge through the power stage by linear biasing or PWM-based pulsed-linear switching on the power module to constitute a short circuit. TI’s isolated gate driver with tri-state capability enables active discharge through a power module using discrete analog circuits.
What is a DC switch in an inverter?
The DC switches allow the inverter controls to connect the IGBTs to the DC source. The DC switches are designed as high duty cycle devices that can open during maximum current flow from the PV array or battery. IGBT Circuit: Provides the conversion from DC to AC. The IGBT bridges used in many inverters today are configured in the B6 configuration.
