20khz Ultrasonic Welding Generator Variable Frequency Manual Ultrasonic Plastic Welding Machine

The power supply of ultrasonic welding drive generator is controlled by the pulse phase shift of the traditional switch trigger circuit, which is complex in circuit, easy to aging in components, and prone to varying degrees of distortion in output waveform, which greatly affects the symmetry of the trigger pulse. A control system composed of microprocessors can complete control tasks in real-time and accurately under the premise of satisfaction. By using software to achieve phase shift control, the symmetry of trigger pulses can be greatly improved and signal accuracy can be improved. Here, DSP is used to achieve PS-PWM control of power. By changing the phase shift angle, a wide range of power regulation is achieved, and the power switching device operates in a soft switching state, greatly improving system efficiency, making it more flexible and reliable to operate.
