Thyristor Power Module

Description:

Thyristor module is a special package mode and with the same property of phase control thyristor. As same principle of phase control thyristor, thyristor module is also the power semiconductor device composed of four-layers materials with three PN junctions and three external electrodes. The electrode lead from the first layer of P-type semiconductor is anode-A, the electrode lead from the third layer of P-type is control electrode gate-G, and the electrode lead from the fourth layer of N-type is cathode-K. It’s advantage in better static characteristics, and especially dynamic characteristics. It’s properly applied in the excitation, electroplating, electrolysis, electric welding, plasma arc drawing, charging and discharging, and voltage stabilization. It can also be used for AC motor soft start and DC motor speed regulation.

Introduction:

1. Package structures of thyristor module manufactured by RUNAU Electronics are compress and solder structures. For the average current more than 160A, the compress-structure thyristor module is highly recommended.
2. Thyristor chip produced under USA manufacturing standard with low VTM, small power consumption and high conversion efficiency.
3. DCB and ALN substrate in high flatness will ensure the strength and stability of compressed combination with thyristor chip, the excellent thermal conductivity, fast heat dissipation, higher anti-impact of surge current and voltage.
4. Base plate was isolated and isolation level upon 2500V to protect human safety.
5. Module appearance of compress structure module is more beautiful. Small size, less weight, easy to install and maintain.
6. Performance of lifetime, working efficiency and characteristics are higher than solder structure module.
7. European mode module package of T series is available to be provided.    

Technical specification：

1. Thyristor module in compress structure manufactured by RUNAU Electronics, range of I_TAV from 90A to 1000A and V_DRM/V_RRM from 1200V to 4500V.
2. The cooling mode of module I_TAV less than 350A is air force cooling while more than 400A is air cooling or water cooling according to requirement of application.
3. In order to ensure the thyristor module operating under the safe condition and normal performance, the current of thyristor module selected is recommended for 2-3 times of rated load current in addition to the load character.  
4. Thyristor module installed on air cooling heatsink, the thermal silica grease is suggested to be spread evenly between the module base plate and heatsink surface.      The fasten force of 4 bolts to fix module on heatsink should be even such the surface of module base plate and heatsink will be connected tightly in order to ensure the heat performance.
