Question

DEAL BEHAVIOR OF FEEDBACK SYSTEMS (15 POINTS In some applications, it is desired to control the converter input terminal curent waveform. The boost converter system of Fig. 2 contains a feedback loop which causes the converter input current i,() to be proportional to a reference voltage v.The feedback connection is a current sense circuit having gain H(s) 0.2 volts per ampere. A conventional pulse width modulator circuit is employed, having a saw- tooth waveform with peak-peak amplitude of -3 V. The quiescent values of the inputs are: 120 V, 2V. All elements are ideal. The compensator has gain G(s)-100s. You may assume that the feedback loop is stable Determine the quiescent values D. I: and,(10points) (a) (b) What is the quiescent value of the error signal v points) 400 H 10 uf 120 2 Hs) 100 LH Transistor gate driver TLs) Reference Fig. 2 Boost converter system with current feedhack, Problem 4
