We assume for the sake of clarity that exactly two independant power sources exist in the vehicle architecture with one being the capacitor bank. The other is referred to as the Lumped Power Sources (PS). Both power sources can source and sink power. In general, the method applies to any combination of two or more direct current electric power sources with at least one being a capacitor bank. A simple block diagram of a representative vehicle architecture is shown below.
