Title:
ENERGY MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/038363
Kind Code:
A1
Abstract:
An energy management system (1) is provided with: a power generation device (20) connected to a HVDC bus (10); a bidirectional DC-DC converter (30) connected to the HVDC bus (10); and an inverter (40) connected to the bidirectional DC-DC converter (30). The bidirectional DC-DC converter (30) is configured by connecting in series a non-insulating chopper converter (31), and an insulating LLC resonant converter (32), and the HVDC bus (10) is connected to a connection point between the non-insulating chopper converter and the insulating LLC resonant converter. The chopper converter (31) transforms a charge voltage of a secondary battery (B1) to a predetermined value, and outputs the voltage to the HVDC bus (10). The LLC resonant converter (32) transforms a direct current voltage inputted from the HVDC bus (10), and outputs the voltage to an inverter (40). Consequently, the energy management system, which is capable of achieving highly efficient voltage conversion and insulation at one time, is provided.
