IRS2092 2X50W Class D Amplifier Project The objective of this work is the design and implementation of the amplifier of class D with an output power 2 x 50 W at the impedance load of 4 Ω and a maximum total harmonic distortion of 10 %. In work is described the principle of operation of amplifiers of class D and are dismembered their sub-blocks. In the other chapters is then made the proposal alone amplifiers. Therefore, the proposal of the preamp, power stage, output filter and also the power supply. The basic principles of audio amplifiers working in class D are known for a number of years. Over time, the topology of these devices modified and refined up to the present forms. Amplifiers of class D are mainly used due to its high efficiency. The application most commonly found in battery-powered systems such as cell phones, MP3 players or laptops.

The involvement of the preamplifier Circuit LM1036 uses to control the dc voltage of the internal reference source formed by Zener diode 5,4 In. The voltage from the diode goes to the pin no. 17, to which are connected the potentiometers POT1 – POT4. Potentiometer POT1 will control the depth, potentiometer POT2 volume, potentiometer POT3 controls the balance and stereo image, and a potentiometer POT4 controls the height. A reference voltage is further governed by physiological compensation volume “loudness controll”, which enable the connection of pins 7 and 12 with the switch S1. For suppression of interfering components in the control circuit.

The circumference of the IRS2092 from the company International Rectifier is designed for control of power transistors MOSFET. In addition to the PWM modulator and exciter transistors is equipped with overcurrent protection and delay circuit, which in turn removes the uncomfortable surges of the speaker.

As the output filter is used filter type low-pass filter consisting of a coil and a capacitor. The involvement of the filter. For the load 4 Ω, the manufacturer of the circuit IRS2092 recommended use the coil of inductance of 22µH and a capacitor of 0.47 µF. The cutoff frequency of the assembled filter we can verify this by using Thompson’s relationship.
