Abstract

The invention discloses a hybrid energy storage system and a generator inverter system. The hybrid energy storage system comprises: a super capacitor; a storage battery which is used for outputting adirect-current power supply so as to provide average power required by the load; and a DC-DC converter, wherein the DC-DC converter comprises a first capacitor, the first capacitor and the super capacitor are connected in series to form a capacitor bank, and the capacitor bank is used for being connected with a voltage bus of the generator inverter system. The DC-DC converter is used for performing corresponding voltage conversion on the direct-current power supply output by the storage battery under the control of the main control unit and outputting the direct-current power supply to the first capacitor, so that the capacitor bank provides peak power required by a load. The hybrid energy storage system can solve the problems that: in the prior art, the working voltage range of a super capacitor in a hybrid energy storage system is narrow, the utilization rate of a storage battery is low, and the system cost is too high due to the fact that the capacity of the hybrid energy storage system is too large.

Description

technical field [0001] The invention relates to the technical field of inverter systems, in particular to a hybrid energy storage system and a generator inverter system. Background technique [0002] At present, automobiles and ships generally use diesel asynchronous / synchronous generators as power sources, and provide power for vehicle-mounted or marine electrical equipment through inverter systems. However, with the continuous improvement of the number and precision of equipment, higher requirements are put forward for power supply capacity and power quality. The existing technology connects the hybrid energy storage system based on DC-DC converter to the voltage of the inverter system. Busbar to realize energy storage and full utilization, so as to meet the needs of ships / vehicle equipment. [0003] However, in the existing hybrid energy storage system based on batteries and supercapacitors, the supercapacitor provides all the impact power to the load through a single co...
