Discontinuous bifurcations in DC-DC converters

DC-DC power electronic converters are usually modelled by switching systems, that means discontinuous systems of Filippov type. These systems are piecewise linear, and simulation is straightforward since analytical solutions are available in each linear topology. Recently, it has been shown that they can undergo some nonstandard bifurcations. In this report, we show that a DC-DC Buck converter can undergo a so-called discontinuous Hopf bifurcation.
