Description
тиристор 1 управл ющего импульса отпираетс вспомогательный тиристор 6, создава ; цепь разр да конденсатора 2 через резистор 4. величину сопротивлени резистора И ,,рыбирают из услови , что к моменту по влени обратного напр жени на тиристоре 1 ток разр да конденсатора 2 должен быть меньше тока удержани вспомогательного тиристора 6.the control pulse thyristor 1 is opened by the auxiliary thyristor 6, creating; The capacitor 2 discharge circuit through the resistor 4. The resistance value of the resistor I ,, is fished out from the condition that by the time of the reverse voltage on the thyristor 1 the discharge current of the capacitor 2 must be less than the holding current of the auxiliary thyristor 6.
Таким образом, потери электрической энергии в предложенном устройстве дл заuiHTbi тиристоров определ ютс главным образом процессом зар да и разр да конденсатора 2.Thus, the loss of electrical energy in the proposed device for cooling thyristors is determined mainly by the process of charging and discharging capacitor 2.
