As is commonly used in daily power components two-way thyristor module, so how to determine the bidirectional thyristor module work where several quadrant? All details are below the bidirectional thyristor module work has four quadrants, in actual work only two quadrant combined into a complete working cycle. Combination is as follows: Ⅰ - Ⅲ, Ⅱ - Ⅲ, Ⅰ - Ⅳ, no Ⅰ - Ⅱ, Ⅱ - Ⅳ, Ⅲ - Ⅳ combination according to G - at the same time T1 and T2 - The polarity of the T1 quadrant to work. General gate is an external circuit ( 1) RC + DB3 the bidirectional thyristor work Ⅰ - at the moment Ⅲ quadrant; ( 2) The photoelectric coupler, the bidirectional thyristor work Ⅰ - at the moment Ⅲ quadrant, characteristic: the trigger signal polarity as the main circuit of ac zero in change. Integration and external is more foot blocks ( Or string of small signal tube) , the bidirectional thyristor module work Ⅰ - at the moment Ⅳ quadrant or Ⅱ - Ⅲ quadrant, characteristic: the main loop of the trigger signal polarity does not follow the alternating current zero. As a result of bidirectional thyristor module itself characteristic, try to avoid Ⅳ quadrant in the application. If work without Ⅳ quadrant, we can recommend the customer choose free buffer quadrant three series of bidirectional thyristor module. Bidirectional thyristor module quadrant distribution and explanation: the first quadrant: T1 ( - ) T2( +) , G relative T1 is ( +) In the second quadrant: T1 ( - ) T2( +) , G relative T1 is ( - ) The third quadrant: T1 ( +) T2( - ) , G relative T1 is ( - - - - - - ) The fourth quadrant: T1 ( +) T2( - ) , G relative T1 is ( +) Bidirectional thyristor module, uphold the do first friend, after doing business, the good faith for this, the quality of the service purpose, respect every visit customers, cherish every met the fate, we build trust with customers of the bridge. Bidirectional thyristor module, you, is worth having. Consultation telephone: 0577 - 62627555!
