Inverter:Hitachi Astemo (Porsche Taycan(2019)) Gate Drive PCB Circuit Analysis Report

Porsche Taycan  (2019)
Extracted from the web	Equipped Inverter Appearance	Equipped Gate Drive Substrate

Overview

• The Porsche Taycan is the company’s first electric vehicle (EV), launched in Europe at the end of 2019 (and in Japan from September 2020) with a price of approximately 12.3 million yen.
• The installed inverter is manufactured by Hitachi Astemo (formerly Hitachi AMS). While Audi e-tron also uses an inverter from the same company, the Taycan’s system supports a battery voltage of 800V (compared to Audi’s 450V). The installed IGBT withstand voltage has been increased from 700V (used in Audi) to 1200V (used in Taycan).
• This report focuses on circuit analysis of the board responsible for inverter control and gate driving.

Product Features

• Drive System: EV with four-wheel drive and two permanent magnet synchronous motors.
  Maximum output: 240kW/326PS (with an overboost output of 300 kW/408 PS).
• The inverter (INV) is slim and mounted on top of the motor, directly connected to the motor using metal bus bars.
• The power module includes Hitachi Astemo’s IGBT module (rated at 1200V).
• LG Energy Solution provides the lithium-ion battery (capacity: 79.2kWh) installed under the floor, resulting in a range of 354–431 km.
