String-Type 215 kW PCS Converter Solution

Pain Points in the Application Scenario

1.1Ie continuous overload capability on both AC and DC sides. AC-side high-voltage ride-through capability up to 1.3Ue for 0.5s. 50kA breaking capacity to ensure AC-side protection for 215kW units.

Value of the Solution

Superior overload current capability ensures stable battery-cabin operation and prevents PCS overload-induced switching-device failures. High-voltage ride-through compliance prevents ESS converter testing and operational faults, mitigating grid-connection risks. High breaking-capacity protection significantly enhances overall system safety.
