In recent years, the application of laser cutting machine power supply in our production and daily life has become increasingly widespread. Perhaps it is not very common or well understood, and the power control mode of laser cutting machines generally refers to the method of stable voltage output. From the sampling quantity, it can be divided into current mode and voltage mode, and from the transfer function, it can be divided into PID and Bang Bang control. Below, the editor will give you a specific introduction to the control mode of the laser cutting machine power supply.

1. The voltage mode is a control mode that samples the output voltage and provides negative feedback.

2. The dual voltage mode is a control mode that samples the output voltage and input voltage for negative feedback.

3. Current mode is a control mode that samples input current and output voltage for negative feedback.

4. A first-order or second-order PID control system is constructed using a sawtooth wave generator and a compensation network for PID control.

5. Bang Bang control generally only uses hysteresis control systems constructed by comparators, also known as hysteresis mode.

The above is about the control mode of the laser cutting machine power supply. Jinan Zhenyu Electronics Co., Ltd. is dedicated to serving you
