Research on the Twin Trawling Test of H-Bridge Power Modules Based on Energy Storage Batteries
This article mainly studies the relevant content of the twin trawling test of H-bridge power modules based on energy storage batteries.Firstly,it introduces the topology design of the main circuit and control circuit,with an energy storage battery connected in parallel on the DC side of each H-bridge power module.Then,it pro-poses the coordination and action principles of the protection of the entire test system:the main controller is re-sponsible for overall protection and its coordination,and the power module,water cooling system and BMS are re-sponsible for their own protection.Finally,it proposes control strategies for the twin trawling of active and reactive power and their specific test processes to achieve the full power test of the active and reactive power of two power modules.
