PWM is a pulse width modulation technology that obtains the required pulse waveform by modulating the pulse width and adjusts the change of signal and energy by adjusting the change of duty cycle. PWM control technology is more and more widely used in the fields of measurement, communication, power control, and transformation. This design uses the simple LM358AD, LF353D, and LMV393M integrated chips as the main components, and designs a PWM control signal generation circuit composed of ordinary electronic components. The circuit is simulated by Multisim14 software, which can realize the output of forward and reverse pulse modulation signals. The circuit has the advantages of low cost, easy to observe the output signal waveform and voltage value of each link, easy expansion of peripheral application circuits, and strong application value.
