Based on the concise introduction of 4q converter principle, a new expected current control is presented. Through this control, not only the input current of converter can be directly controlled, but also the frequency of switch device is kept constant, and the implementation becomes easy. At first, this method was simulated through computer, and the simulated result indicated its feasibility and good dynamicstatic performance.The system experiment was performed on the basis of simulation. The wave contrast of simulation and experiment indicated the validity of simulated result and showed that this method could completely meet the needs of 4q converter design.
