This paper proposes an isolated full bridgeless single stage alternating current-direct current (AC-DC) converter. The proposed converter integrates the operation of a pure bridgeless power factor correction with input boost inductor cascaded with center-tap transformer and half bridge circuit. In addition, the bidirectional switch can be driven with single control signal which further simplifies the controller circuit. It is also proved that this converter reduces the total number of components compared to some conventional circuit and semi-bridgeless circuit topologies. The circuit operation of the proposed circuit is then confirmed with the small signal model, large signal model, circuit simulation and then verified experimentally. It is designed and tested at 115 Vac, 50 Hz of input supply, and 20 Vdc output voltage with maximum output power of 100 W. In addition, the crossover distortion at the input current is minimize at high input line frequency.

“…However, the slow input bridge diodes and bulky DC link capacitor significantly leads to power losses. The proposed single stage semi-bridgeless converter without bulky DC link capacitor [7], [8] significantly reduce the converter power losses. Thus, improved the conversion efficiency with less components count.…”

“…In this paper, the small-signal of a bridgeless AC/DC converter with bidirectional switches as depicted in Figure 1 is presented. The full bridgeless of the proposed circuit topology eliminated the bridge rectifier of a conventional circuit topology and the semi-bridgeless diodes [7], [8] in a conventional bridgeless circuit. The idea of the proposed converter is based on the primary side [18] but without diodes presented which further eliminate the line frequency rectifier losses.…”

A small-signal analysis of a single-stage bridgeless boost half-bridge alternating current/direct current (AC/DC) Converter with bidirectional switches is performed using circuit averaging method. The comprehensive approach to develop the small signal model from the steady state analysis is discussed. The small-signal model is then simulated with MATLAB Simulink. The small-signal model is verified through the comparison of the bode-plot obtained from MATLAB Simulink and the simulated large signal model in piecewise linear electrical circuit simulation (PLECS). The mathematical model obtain from the small-signal analysis is then used to determine the proportional gain K_p and integral gain K_i. In addition, the switch large-signal model is developed by considering the current and voltage waveforms during load transients and steady-state conditions.
