An approach to the modeling and regulation problem of a buck converter which relies on its hybrid nature is presented. The buck converter is modeled as a switched affine system. Then, using the stored energy in the inductor and the capacitor as the common Lyapunov function, switching rules and activation region of all the subsystems are defined to assess(More)
Two new pulse width modulation (PWM) schemes: chaos-based sinusoidal PWM (SPWM) and chaos-based space vector PWM (SVPWM) are brought forward. There are cluster harmonics around the multiples of switching frequency in conventional SPWM and SVPWM output waves owing to their fixed switching frequencies. Chaos-based PWM strategies utilize a chaotic changing(More)
