Amplifier 4×60 Watts. To its solution was first selected integrated circuit LM3886T. The proposal continued the calculations and the election of the additional components of the integrated circuit and the design of printed circuit connections. To the end amplifier was also designed system of active cooling. In the fourth chapter was made the proposal of the converter voltage. It was first designed portion control circuit on a separate printed circuit board with adjustable frequency and duty cycle of switching pulses.
Car Amplifier Circuit Schematic
DC DC Converter circuit (2x30v) For this activity was selected by the integrated circuit SG3525, which enables modulation of the duty cycle of the generated waveform by applying the output voltage of the converter. After it was designed the power part of the converter voltage in the topology of push-pull with a transformer on a toroidal the core and MOSFET transistors. The power part was also designed on a separate board the printed circuit board.
