Week 4 Session 5

1.DC-DC Converters for Accessory Systems:

A DC-DC converter steps down the high-voltage DC from the traction battery to provide power to the 12V electrical system, including the horn.

2.DC-AC Inverters for Traction Motors:

Traction Motors: The primary propulsion system in an EV uses high-voltage DC power from the battery. DC-AC inverters are used to convert this DC power into AC power to drive the electric traction motors. These inverters allow for precise control of motor speed and torque.

3.Onboard Charger:

Onboard Charger: When charging an EV from an AC power source (e.g., a home or public charging station), the vehicle's onboard charger converts AC power into DC power to charge the traction battery. These chargers come in various power ratings, depending on the charging speed.
