In this paper, smooth transition between buck and boost modes in 4-switch non-inverting buck-boost power converter is investigated. It is shown, both theoretically and on an experimental converter prototype, how pulse-width modulator (PWM) maximum and minimum duty cycle limitations can result in pulse skipping at the mode transition and substantial increases in the output voltage ripple. This is a very significant problem when the converter is used as a power supply for WCDMA RF power… CONTINUE READING
