Study on Control Technique of Dynamic Hysteresis for Active Inverter

Based on the circuit topology of the grid-side converter, the control model of the grid-side converter is established, control technique of dynamic hysteresis for active inverter is analyzed, meanwhile, the relationship among feedback currents, the inductance, the maximum given current and the minimum given current, the difference value between DC bus voltage and network voltage is derived. The experimental system with DSP core is developed. Theory analysis and simulation results show that the control technique is feasible, which has some practical values.
