Abstract
P and PI control methods are widely used in the closed-loop con-trol of the inverters in various power electronic equipment. How-ever, PID control method is barely adopted. In this paper, from an in-depth analysis of the operation and control processes of pulse width modulation (PWM) inverter, it is verified that PID control method is not suitable for inverter control. And the theo-retical process gives birth to a new control method, which is simi-lar but not identical to PID control method, therefore, it is named as pseudo-PID control method. For fundamentality and generali-ty, the pseudo-PID control method is derived from the single-phase PWM inverter, which is the basis of three-phase or multi-level inverters. To verify the performance of the pseudo-PID con-trol method, it is applied to a single-phase PWM inverter for relay testing. The simulation and experimental results demonstrate that with the aid of pseudo-PID control method the accuracy of the output current of the inverter is already comparable to that of the linear power amplifier (LPA), which makes the application of inverter in relay testing feasible. Considering the higher efficiency and simpler structure of the PWM inverter, it can make the relay testing device more cost-effective.
