摘要
Abstract
In this paper,the small signal model for dual-Buck inverter as well as its control scheme is developed,and a regulation of voltage and current feedback loop with resonant controller is researched.The current inner loop is controlled by hysteresis,which has the characters of simple implementation,a rapid dynamic response and unconditional stability.Voltage outer loop ensures sinusoidal output voltage with good reliability and steady-state properties.In addition,the introduction of resonant controller makes the system output external characteristics significantly improved.Compared with the traditional method of using current feed-forward loop to improve the load disturbance rejection capabilities,this new method improves the steady-state performance and saves the cost without the additional control loop.Simulation and experimental results verify the correctness of the theoretical analysis.The system achieves a better output waveform quality,fast dynamic response,precise regulation accuracy,and high efficiency.关键词
