Description

дах транзисторов усилител 4 мощности из-за изменени сопротивлени нагрузки. rows amplifier transistors 4 of power due to variations of load resistance. При достижении напр жени на коллекторно-эмиттерном переходе каждого из транзисторов усилител мощности величивы напр жени стабилизации стабилитронов И, дальнейший рост напр жени прекращаетс . Upon reaching the voltage on the collector-emitter junction of each transistor power amplifier velichivy voltage stabilizing zener And, further growth is stopped voltage. 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. This reduces power dissipation transistors, prevents them from a failure and increases reliability, this apparatus as a whole during operation of Bytes different 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. To conduct electrosurgical interventions amplifier is connected to the output electrode 6. After summing it to include a predetermined range of high frequency current pedal, and at the contact electrode 6 to the tissue dissection occurs last or coagulation depending on the predetermined power. Аппарат рассчитан на выходную мощность 60 Вт и ропротивление нагрузки от 0,5. The device is designed for an output power of 60 W and a load of 0.5 roprotivlenie. кОм до 20 кОм. kohm to 20 kohm.

Таким образом, при сн тии нагрузки (отрыв электрода от тканей) либо ее резком Thus, upon release of the load (peel the electrode from the tissue) or its sharp

увеличении (т. е. более 20 кОм) транзисторы будут предохранены от выхода из стро , что повысит надежность аппарата. magnification (m. e. more than 20 kilohms) transistors are protected against fails, which increases reliability unit.
