Introduction
The Electrical Machine Electronics (EME) is primarily used as control
electronics for the electrical
machine. It is also responsible for converting the direct current voltage from
the high-voltage b

Introduction
The electrical machine in the G20 PHEV is a permanently excited synchronous
machine. It can convert
electrical energy from the high-voltage battery unit into kinetic energy, by
which the vehicle is driven.
Both electric driving up to approximately 87 mph (140 km/h) as well as support
