This paper describes a direct-power-controlled current-source PWM rectifier, and presents its experimentally examined operation characteristics. The most important feature of this strategy is a direct selection of switching states of the PWM rectifier on the bases of instantaneous control errors of active and reactive power. In addition, this paper describes a theoretical analysis on relationship between the instantaneous power and the switching states, which is essential to compose a switching-state table in the controller. Feasibility of the proposed strategy is verified through experimental tests, using a 2-kW prototype setup. As a result, the maximum total input power factor of 99.86% and the maximum total efficiency of 92.72% have been confirmed in the tests as well as high-speed responses of the power.
