The authors apply digital control theory to power electronics in a manner thoroughly different from the traditional, analog control scheme. In order to apply digital control theory to power electronics, the authors define a number of new parameters, including the energy factor, pumping energy, stored energy, time constant, and damping time constant. These parameters differ from traditional parameters such as the power factor, power transfer efficiency, ripple factor, and total harmonic distor 606 $aPower electronics 606 $aDigital electronics 606 $aDigital control systems 615 0$aPower electronics. 615 0$aDigital electronics. 615 0$aDigital control systems. 676 $a621.317 700 $aLuo$b Fang Lin$0917284 701 $aYe$b Hong$f1973-$01170524 701 $aRashid$b M.
