| Abstract: | By adopting the system functions of PLC, calling PID control algorithm software module and adding integral separation algorithm, etc., the calculated result is converted into internal time value of timer. The time value is output through PWM to control cycles of sine wave for regulating power. Thus the closed loop power regulation and temperature control are achieved. |
