The working principle of Class D amplifier:

The working principle is similar to the switching power supply, and the asynchronous modulation method is used.

The input terminal is the analog signal and the triangular wave of the triangular pulse signal generator is modulated into pulse width modulation waveforms with unequal widths through the comparator.

Class D amplifier modulates the audio frequency below 20KHz into PWM signal, and the frequency of the triangle wave must reach at least 200KHz, after correction, output to the switch tube for voltage and current amplification.

The amplified high-frequency digital signal is passed through a high-quality low-loss low-pass filter to restore the high-power PWM signal to an audio power signal, thereby driving the speaker to complete the work of converting electrical energy into sound energy.

We have made 1 IR2092 Class D amplifier PCBA:

PCBA size 85*65mm, OSP, green oil, white character, BOM list is confidential.

The advantages of this amplifier are low cost, high power, high efficiency, no heat, and the power can reach 600 watts to 1000 watts.

Some people say work efficiency is 100%, we measure about 85% (of course, it is not the only criterion to measure the quality of amplifier).

Because of the above advantages, it is very popular in the entertainment industry.

Xianglong (Shenzhen) Electronic Technology Co., Ltd supports customized production of amplifier PCBA, whether it is Class A, Class B, Class AB, or Class D amplifier PCB/PCBA, we will strictly follow the ISO9001 quality management system to help you manufacture, if You have related needs and questions, don't hesitate to contact us immediately!
