Abstract :
DC-DC converters operating in parallel have been proved to have dynamics different from that of a single converter. In this paper, Hopf bifurcation is investigated for a system of two boost converters operating in parallel under current mode control. Although two converters operating in parallel increase the efficiency of the system, if the control parameters are not chosen properly, the system becomes unstable and starts to oscillate
