Abstract

A power management system with DC/AC converter for providing power to electrical heating, ventilating and air-conditioning system, having a first electrical power interface (EPI) and a second EPI. Optional DC/DC converter having a third EPI and a fourth EPI, the third EPI being electrically coupled to the second EPI. A switching arrangement of the system has a common connection, the common connection being configured to be coupled to an electromagnetic machine, a first connection selectively electrically coupled to the common electrical connection, the first electrical connection further being electrically coupled to the second EPI and the third EPI, and a second electrical connection selectively electrically coupled to the common electrical connection, the second electrical connection further being electrically coupled to the fourth EPI. The first EPI, the second EPI, the third EPI, the fourth EPI and the common electrical connection are configurable as electrical power inputs and outputs.
