Prius Repairs We Offer in Las Vegas
The hybrid inverter, also called the power control unit, is one of the most critical — and most expensive — components in your Prius or hybrid vehicle. It converts your high-voltage battery's DC power into the AC power your electric motor needs to drive the wheels, and it manages power flow between the battery, motor, and generator during acceleration, cruising, and regenerative braking. Inside the inverter, a set of IGBT power transistors and capacitors handle this conversion thousands of times per minute.
ecause the inverter works constantly and generates significant heat, it's vulnerable to failure from age, heat cycling, and — most commonly — a failed inverter coolant pump. When an inverter fails, dealership replacement costs can run into the thousands of dollars. At Prius Battery Repair LV, we diagnose inverter problems accurately and offer repair and rebuild options that can save you significant money over a full dealership replacement.
