Description
Усилитель мощности звуковой частоты класса D построенный на базе микросхемы IRS2092. Выходная мощность около 250-300 ватт на нагрузка 4 Ома, рекомендованная рабочая частота 350-400 кГц, присутствует защита от короткого замыкания в нагрузке. Схема рассчитана на работу с полевыми транзисторами IRFB5615, при использовании других транзисторов необходимо пересчитать некоторые номиналы. Усилитель при правильной сборке работает сразу, требуется только настройка желательной рабочей частоты переменным резистором. Для питания Усилителя необходим источник питания с силовым двухполярным выходным напряжением 35-50 вольт (допускается до 55 вольт) с силой тока 2.4 Ампер на один канал, и слаботочное напряжение 12 вольт для питания логики.
Дроссель намотан на сердечнике Т106-2 проводом 1 мм количество витков 56
Class D audio frequency power amplifier based on the IRS2092 chip. Output power about 250-300 watts per 4 Ohm load, recommended operating frequency 350-400 kHz, there is protection against short circuit in the load. The circuit is designed to work with field-effect transistors IRFB5615, when using other transistors it is necessary to recalculate some denominations. The amplifier at the correct assembly works at once, only adjustment of desirable operating frequency by the variable resistor is required. The power supply of the Amplifier requires a power supply with a power bipolar output voltage of 35-50 volts (up to 55 volts is allowed) with a current of 2.4 Amperes per channel, and a low-voltage voltage of 12 volts to power the logic. The choke is wound on the core T106-2 wire 1 mm number of turns 51
