Wärtsilä MV Power Drive
Especially designed for marine and offshore applications, the modular design allows easy installation and maintenance
Wärtsilä Medium Voltage Power Drive is especially designed for marine and offshore applications. The modular design allows easy installation and maintenance.
The Wärtsilä Medium Voltage Power Drive can be used as a control device in applications such as marine propulsion and thrusters, large fans, pumps, compressors and hoists. It can control asynchronous, synchronous and permanent magnet machines in generator or motor mode.
The drive is based on press-pack IGBT transistor technology with 3 level PWM inverter control. The modular IGBT design has large overload capacity, integrated gate driver boards, and a plug-in bus bar connection.
