US 2017/0256957 A1 · HYBRID POWER DELIVERY WITH IMPROVED POWER CONTROL

Abstract

Disclosed herein are systems, devices, and methods for a hybrid power delivery system with improved energy storage system power control. The hybrid power delivery system may comprise a generator coupled to a variable frequency drive, in which a first power converter converts a first AC power from the generator to a DC power at the DC bus coupled to the first power converter. The DC bus is coupled to a second power converter, which converts the DC power to a second AC power. Also coupled to the DC bus is a power controller, which is also coupled to an energy storage system. The power controller is configured to regulate power flow between the energy storage system and the DC bus. The power controller may comprise at least one of a switch, a chopper circuit, a contactor, a silicon controlled rectifier, and/or a DC-to-DC converter.
