Abstract
A DC–DC synchronous buck–boost converter that is capable of operation with or without dead or overlap-time is proposed. The topology of the converter is derived from the topology of quasi-impedance source converter where two capacitors and two inductors are used for second-order filtering and energy storage. However, its gain is identical to that of the conventional buck–boost converter (BBC), thereby qualifying it as a BBC. The elimination of dead or overlap-time reduces control complexities and permits higher frequency operation which implies the use of smaller capacitors and inductors. Operation of the converter was successfully verified using control signals without dead or overlap-time using a 50 kHz prototype and its output voltage is compared with the ideal theoretical values.
