This paper deals with the voltage control of DC-DC cascaded buck converters. A steady-state analysis is presented, providing the design guidelines for all the parameters of two cascaded buck converters based on analytical expressions. In the sequence, a state feedback model of the converter is obtained, and after linearized. A small-signal model in the(More)
The use of pulse width modulation with selective harmonic elimination (SHE-PWM) in cascaded H-bridges (CHB) multilevel converters allows the reduction of the output current distortion by the elimination of low order harmonic components. However, voltages produced by CHB modules to synthesize the SHE-PWM pattern is an issue that deserves deeper(More)
