The Application of CW32F030 Series MCU in Electric Welding Machines

This article will introduce the application of Wuhan Core Source Semiconductor CW32F030 series microcontroller in arc welding machines. The interference in the welding industry site is too strong, so there are high requirements for the anti-interference of MCU. The reliability of all ESDs of Wuhan Core Source Semiconductor's MCU has reached the highest level of international standards, and HBM ESD has passed the 8KV test with strong anti-interference ability.

Application of CW32F030 in LED PWM Dimming Control Board

PWM output control based on microcontroller CW32 is achieved through RC hardware circuit and timer combined with software to achieve PWM output control with adjustable duty cycle and fixed cycle. The general process is to use a potentiometer to change the duty cycle, and through AD conversion, the duty cycle of the PWM square wave is sent to the LED for display. Then, the PWM waveform generated by the given duty cycle is input into a low-pass filter, which converts the input digital signal into an analog signal and then controls the gradient of the LED light.

Combustible gas detector

Based on the high-precision ADC of CW32F030C8T6, it has the characteristics of fast conversion speed, high reliability, strong anti-static, and strong anti-interference.

Application of CW32F003 series products on level switches

As the main control unit of the material level switch, CW32F003F4P7 drives the vibration components to generate a certain oscillation frequency. When there is a change in liquid level, it causes a change in oscillation frequency. CW32F003F4P7 detects this change, outputs a switch signal to the equipment main control unit, and then senses the liquid level situation. CW32F003F4P7 also controls the input and output of external signals, prompting operators to timely understand the liquid level situation and make accurate judgments.
