- 説明
Power inverter (DC-AC) is a key component for building cascaded high-voltage frequency converters.
Its primary function is to convert three-phase 690 V AC into single-phase 680 V AC with a specified amplitude, frequency, and phase, ensuring high output quality for powering high-power high-voltage motors (6 kV and above).
Technical features:
- Power circuit: includes a three-phase diode-module rectifier and a single-phase voltage-source inverter built on two half-bridge IGBT modules. The use of IGBT switches guarantees high reliability and low losses.
- Cooling system: an efficient heatsink with forced air cooling ensures a stable thermal regime for the power modules under intensive operating conditions.
- Control: equipped with driver boards for precise control of IGBT modules, which is essential for generating a high-quality PWM signal.
- Adaptability: designed for operation in climatic version UL, placement category 4, confirming its resilience to harsh operating conditions.
- Configuration flexibility: can be supplied with snubber circuits, voltage dividers, and current, voltage, and temperature sensors, allowing the module to be tailored to specific customer requirements.

- 用途
Power inverter block is designed for use as part of cascaded multilevel frequency converters (CMFC).
In such systems, multiple identical power modules are combined to generate a high-voltage (6–10 kV) high-quality output, enabling efficient control of high-power electric motors.
This solution is in demand across the following industries and applications:
- Heavy industry: for soft starting and energy-saving control of fans, induced-draft fans, compressors, pumps, and conveyors at mining and metallurgical plants.
- Power generation: in auxiliary systems of thermal and hydroelectric power plants for controlling feedwater, circulating, and network pumps, as well as forced-draft fans.
- Public utilities and water management: for controlling high-power pumping units in water supply and drainage systems, preventing water hammer and reducing energy consumption.
- Oil, gas, and chemical industries: for driving centrifugal compressors, liquid-transfer pumps, and other critical equipment.
The use of cascaded frequency converters based on such inverters ensures a sinusoidal output voltage waveform, reduces stress on motor insulation, and extends equipment service life.
