Design and Realization of Special Hybrid Intelligent Power Module Based on Thyristor

摘要：

Aiming at various problems of capacitor devices in low-voltage reactive power compensation, a concept of SHIPM(Spedal Hybrid Intelligent Power Module ) based on thyristor was proposed. This design used for reference of the integrated technology of IPM (intelligent power module) to improve the reliability leveL The optimized control circuit, driving circuit, protective circuit, thyristor and high-powered magnetic latching relay were packaged in whole . as appropriative intelligent power module. The module used the parallel connection of the thyristor and magnetic latching relay in the main loop and enabled the thyristor and relay to work cooperatively through the control circuit of single-chip ATMEGA8L. First the thyristor was conducted when the voltage crossed zero. Then as a result of the close of the magnetic latching relay, the electric current was taken on by the magnetic latching relay alone. The module has the advantages of low power consumption, low surging current, strong capability of the anti-harmonic,quick response speed and high reliability. In the test of switching 30Kvar capacitance, the surging current was about 1.1 times the peak value of stable current > and the rise of temperature was smaller than 18 degree centigrade. The paper described the construction, basic principle, and performance of the circuit, and analyzed the performance of the circuit
