9.7 Design of a boost converter with current feedback and a PI compensator. In some applications, it is desired to control the converter input terminal current waveform. The boost converter system of Fig. 9.57 contains a feedback loop which causes the converter input current ig(t) to be proportional to a reference voltage vref(t). The feedback connection is a current sense circuit having gain H(s) = 0.2 volts per ampere. A conventional pulse width modulator circuit (Fig. 7.29) is employed, havin
