C A novel universal loss-reduce scheme, namely Dead-Band-Logic is presented. When a traditional method is used, the loss-reduce can only be realized via Space-Vector-Modulation , and the effect of loss-reduce depends on the power factor angle. The DBL can implement loss-reduce only by digital circuit and only need to know the direction of three phase currents.

论文中提出的降耗逻辑只需知道三个电流的方向，仅用数字电路就能实现降耗，此法能自动适应功率因数角的变化，适合于单片机控制，也适合于模拟控制。
