The GE MVR1600-4601 is an air-cooled rectifier, with relevant information as follows:
- Rated Voltage: 690Vac
- Rated Current: 1600Adc (nominal)
- Cooling Method: Air cooling
- Other Features: The module has no user-serviceable components and is equipped with a pre-charge protection circuit.
- Industrial Automation: Used to provide stable DC power for medium-voltage motors and drive equipment. For example, in production lines of large factories, it powers various devices such as motors, pumps, and fans to ensure stable operation of the production process.
- Power Transmission and Distribution: In power systems, it converts alternating current (AC) to direct current (DC) to meet the power supply needs of specific equipment. For instance, it serves as a DC control power system in some substations, providing electricity for control and protection devices of switchgear.
- Renewable Energy Sector: Applied in wind and hydropower generation systems for rectification and power conversion to improve energy efficiency. After converting AC generated by generators to DC, it enables further energy storage or grid-connected transmission.
The GE MVR1600-4601 air-cooled rectifier realizes rectification based on the unidirectional conductivity of thyristors and diodes. When AC is input, the thyristors conduct under the control of an appropriate firing angle, while the diodes maintain unidirectional conductivity at all times. This ensures current flows only in one direction, thereby converting AC to DC. By adjusting the firing angle of the thyristors, the magnitude of the output DC voltage can be regulated to meet the requirements of different loads.
