Research on Control Performance of Sinusoidal Inverter of Mine Storage Battery

摘要：

Based on sinusoidal inverter of mine storage battery, the control performance of inverter was analyzed and researched. The current characteristic of inverter was changed when different load being driven; therefore, the approximate transfer function models were built up for inverter outputs under different loads. The quality of output waveform was difficulty to be controlled because system damping was lower, and use of the capacitor current feedback control could effectively increase damp of the system. The inverter was based on PID control and equipped with capacitor current feedback control, which solved the adaptability problem of inverter under different loads and improved the quality of waveform. In this paper, the implementation scheme of control circuit was presented; the simulation analysis and experiment were carried out for the system, which could provide reference for engineering design.
