Advantages of Speed Control Controller for Electric Locomotive

1. Smooth motion with soft start function.
2. Energy saving is remarkable: resistance speed regulation is realized by resistance voltage divider, and a large part of the loss is on resistance, while field-effect on-voltage of IGBT chopper speed regulation technology consumes very little energy, and almost all of the energy is used in motor work, which can save more than 30%.
3. Protection battery: When the voltage is too low, the current drop value is reduced by 50%. That is to say, it has the function of under-voltage protection, so as to protect the battery from being damaged by over-discharge, thus prolonging the life of electric shock.
4. It has good linearity and long service life.
5. Modular design is adopted in the main box, which makes maintenance simple and convenient.
6. The driver is easy to operate.

At present, the most widely used IGBT DC chopper in the market is full-controlled chopper. Its main device is IGBT, which is an advanced power electronic device in the world. It is controlled by gate voltage, and fundamentally overcomes the shortcomings of thyristor chopper and GTR chopper. The chopper not only can be used as speed regulating device for Narrow-gauge Locomotive in coal mine, but also can be used for other DC loads which require adjustable supply voltage according to different load objects. Compared with silicon pulse speed regulation mode and resistance speed regulation mode, it has obvious advantages.
