Switching Rule Design for DC-DC Converters with Mode-Dependent Average Dwell Time

The switching rule with mode-dependent average time (MDADT) for DC-DC Buck converter are mainly designed in this paper. The traditional switching rule doesn't consider the use of slow switching. In terms of control theory, the slow switching mode can also make the systems stable because the switching signal combined with MDADT keep the system stable asymptotically. Moreover, the chattering problem of sliding mode can be suppressed. Performance of the system is evaluated according to a series of simulations.
