A system is described for controlling the flow of electrical power between two sources. The system includes a circuit coupled between a first source and a second source and a controller subsystem coupled to the circuit. The circuit is capable of transitioning, in a continuous manner, between a first direction wherein electrical power flows from the first source to the second source and a second direction wherein electrical power flows from the second source to the first source. The control subsystem generates control signals to selectively activate switching elements of the circuit to control the direction and the amount of electrical power flowing through the circuit between the first and second sources.

Bi-directional power supply circuit

A power generation system is described for supplying electrical power to a load from at least one of a generator and a battery. The power generation system includes a power bus coupled to the generator and a bi-directional conversion unit coupled between the power bus and the battery. The bi-directional conversion unit is capable of transitioning between a first direction wherein electrical power flows from the power bus to the battery and a second direction wherein electrical power flows from the battery to the power bus.
