Description
дах транзисторов усилител 4 мощности из-за изменени сопротивлени нагрузки. При достижении напр жени на коллекторно-эмиттерном переходе каждого из транзисторов усилител мощности величивы напр жени стабилизации стабилитронов И, дальнейший рост напр жени прекращаетс . Это снижает мощность рассе ни на транзисторах, предохран ет их от выхода из стро и повышает надежность в,сего аппарата в целом при его работе Б различных режимах.dach transistors of power amplifier 4 due to a change in load impedance. When the voltage across the collector-emitter junction of each of the transistors of the power amplifier is high, the stabilization voltage of the zener diodes And, the voltage increases further. This reduces the power dissipation of the transistors, protects them from failure and increases the reliability of this device as a whole when it is working in various modes.
Дл проведени электрохирургических вмешательств к выходному усилителю подключаетс электрод 6. После подведени его к определенному участку педалью включают высокочастотный ток, и в местах контакта электрода 6 с тканью происходит рассечение последней или коагул ци в зависимости от заданной мощности. Аппарат рассчитан на выходную мощность 60 Вт и ропротивление нагрузки от 0,5. кОм до 20 кОм.Electrode 6 is connected to the output amplifier to conduct electrosurgical interventions. After leading it to a certain area, the high-frequency current is turned on by the pedal, and at the points of contact of electrode 6 with tissue, the latter is dissected or coagulated, depending on the set power. The device is designed for an output power of 60 W and a load resistance of 0.5. kOhm to 20 kOhm.
Таким образом, при сн тии нагрузки (отрыв электрода от тканей) либо ее резком Thus, when the load is removed (separation of the electrode from the tissues) or its sharp
увеличении (т. е. более 20 кОм) транзисторы будут предохранены от выхода из стро , что повысит надежность аппарата.The increase (i.e. more than 20 kOhm) transistors will be protected from failure, which will increase the reliability of the device.
