Abstract

A vehicle electrical system is equipped with an inverter, an electrical energy store, an electrical machine and an AC transmission terminal. The inverter has a first and a second side and is configured to transmit power between these sides. The first side of the inverter is connected to the energy store via input current terminals of the inverter. The second side of the inverter is connected to the electrical machine via phase current terminals of the inverter. The inverter has at least two H-bridges. Each of the H-bridges bypasses the two sides of the inverter. The AC transmission terminal is connected to the second side of the inverter.
