International ClassH02M 007/217AbstractA bridge rectifier circuit uses active switches for at least two of its four rectifying elements, and employs an active control circuit to control the state of the active switches. The active control circuit receives its input from the AC input to the bridge rectifier circuit, is powered by the DC output of the bridge rectifier circuit, and provides control outputs to the active switches. In this manner, a bridge rectifier circuit having improved performance and decreased power dissipation is achieved.Other References
