High-power high-voltage inverter

1. Power unit cabinet

Main components: power unit (including HV-IGBT), current sensor, water cooling pipeMain functions: Through the control of HV-IGBT, the frequency conversion speed regulation function and the unit automatic bypass function are realized; based on the carrier phase shift technology, the power units output perfect sine wave in series; the pipeline has a built-in cooling medium, which is driven by the circulating pump The heat inside the unit is transported to the radiator.

2. Water cooler

Main functions: The main circulation pump promotes the reciprocating circulation of the cooling medium between the air radiator and the power device to achieve the heat dissipation effect; the circulation pipeline is equipped with a high-level water tank as a voltage regulator buffer device to maintain a constant pressure for the system and absorb the cooling medium in the system The volume changes to ensure the normal operation of the entire system.Main components: main circulation pump, filter, circulation pipeline, air radiator.

3. CONCEPT drive circuit and busbar design

Higher reliability, higher power density, lower voltage spikes.

4. Typical load:Loads such as blast furnace blower, oxygen compressor, boiler induced draft fan, sintering main exhaust fan, fan, and water pump.
