Description
пульсного модул тора, транзисторы предварительного мостового усилител 5-8, обратные диоды 9, 10, конденсаторы емкостного делител 11, 12, трансформаторы 13, 14, запирающие диоды 15, ограничительные резисторы 16 и двухтактный усилитель мощности 17.pulse modulator, transistors of pre-bridge amplifier 5-8, reverse diodes 9, 10, capacitors of a capacitive divider 11, 12, transformers 13, 14, blocking diodes 15, limiting resistors 16 and a push-pull power amplifier 17.
Инвертор работает следующим образом.The inverter works as follows.
Задающий генератор 1 вырабатывает только напр жени , необходимые дл питани щиротно-импульсного модул тора 2, на выходе которого формируютс два пр моугольных напр жени с регулируемым фазовым сдвигом. Выходные трансформаторы 3, 4 подключены через ограничительные резисторы непосредственно к выходам модул тора . Такое включение позвол ет исключить сквозные токи через транзисторы 5, 7 и 6, 8.The master oscillator 1 generates only the voltages required to supply the pulse-width modulator 2, the output of which produces two rectangular voltages with adjustable phase shift. Output transformers 3, 4 are connected via limiting resistors directly to the outputs of the modulator. This inclusion eliminates the through currents through the transistors 5, 7 and 6, 8.
Напр жени на трансформаторах 3, 4 представлены на фиг. 2 (Оз, U). Транзисторные стойки 5,7 и 6, 8 переключаютс попарно-поочередно , поэтому напр жени на отпирающем 13 и запирающем 14 трансформаторах имеют вид соответственно t/js и t/14. Во врем паузы в напр жении :Uis первична обмотка трансформатора 13 закорочена открытым транзистором, например 5, и диодом 9. Форсированное запирание силовых транзисторов осуществл етс посредством трансформатора 14, вторичные обмотки которого соединены со входами силовых транзисторов усилител мощности через запирающие диоды. Потребление мощности во врем паузы в управл ющем напр жении не превыщает полезной мощности управлени .The voltages on transformers 3, 4 are shown in FIG. 2 (Oz, U). The transistor racks 5.7 and 6, 8 are switched in pairs and alternately, therefore the voltage on the unlocking 13 and locking 14 transformers look like t / js and t / 14. During a pause in the voltage: Uis, the primary winding of the transformer 13 is shorted by an open transistor, for example 5, and a diode 9. The forced locking of the power transistors is carried out by means of a transformer 14, the secondary windings of which are connected to the power transistors of the power amplifier through locking diodes. The power consumption during a pause in the control voltage does not exceed the effective control power.
