This paper presents a high-efficiency positive buck–
boost converter with mode-select circuits and feed-forward techniques.
Four power transistors producemore conduction andmore
switching losseswhen the positive buck–boost converter operates in
buck–boost mode. Utilizing the mode-select circuit, the proposed
converter can decrease the loss of switches and let the positive
buck–boost converter operate in buck, buck–boost, or boost mode.
By adding feed-forward techniques, the proposed converter can
improve transient response when the supply voltages are changed.
