thyristor

Thyristor, diode and other power electronic equipment, so that the chip parameters have a very close relationship with its environmental conditions, in the high altitude, low temperature environment, users need to pay attention to the correct use of the method to ensure the reliable operation of the equipment. Thyristor modules are often referred to as power semiconductor modules. The module principle was first introduced into the field of power electronics technology in 1970 by Ximenkang Company, which is a high-power semiconductor device with four-layer structure and three PN junctions in the form of module packaging. The bridge module encloses the rectifier tube in a shell. Full bridge and half bridge. The full bridge is the four diodes of the connected bridge rectifier circuit sealed together. Half bridge is to seal the half of the four diode bridge rectifier together, with two half Bridges can form a bridge rectifier circuit, a half bridge can also form a transformer with the center tap full wave rectifier circuit, the selection of rectifier bridge to consider the rectifier circuit and working voltage. Industrial solid state relay 100% load current aging test, through the European Community CE certification, international ISO9000 certification, 3C certification.

When used at high altitudes and low temperatures, attention should be paid to:

1. At -40℃ at control temperature, SCR gate trigger current value exceeds 25℃, about 30% of the gate trigger voltage is doubled in order to ensure the required trigger sufficient strength silicon gate current reliable starting device. We ask triggered users to take effective action. This also improves the equipment?? The performance of? The di/dt, in order to reduce opening time and opening loss, allows the parallel operation of the series or the device to play an important role. Recommended gate trigger extreme conditions: gate trigger current amplitude IG = 10IGT (2-5A, tr≤1μs gate current opening.

2. Under the condition of high altitude, the development ability of air-cooled radiators will be reduced, but the lower environmental stability will help students to improve the heat dissipation of devices. Therefore, Chinese enterprises can fully consider the selection of devices and radiators according to the different temperature data of the construction site and the highest environmental problems that we may affect the company. To have a certain social work current margin.

Figure 3. If the equipment management of the enterprise needs to start and stop frequently, the equipment can cycle frequently between -35c and -125c, and the life and reliability of the equipment will be reduced compared with the normal development work, and it should be paid attention to when using.

The company produces and various different specifications and models of thyristor intelligent management module, relay control module, bridge arm module, rectifier bridge module, various control cabinets and trigger boards, control boards and other supporting modules of the main products, sincerely look forward to cooperating with the company and purchasing staff to provide low-cost, reliable quality development of electronic components.
