Abstract:
The conventional two-stage power converters with bridge rectifiers are inefficient and may not be practical for the low-voltage piezoelectric generators. In this paper, a single-stage ac–dc power electronic converter is proposed that avoids the bridge rectification, dc-dc converter and directly converts the low ac input voltage to the required high dc output voltage at a higher efficiency. The topology combines a boost converter and a buck-boost converter to condition the positive and negative half portions of the input ac voltage, respectively. Only one inductor and split filtering capacitor are used in both circuitries to reduce the size of the converter control schemes are proposed to operate the converter. The input ac voltage with 0.4-V amplitude is rectified and stepped up to 3.3-V dc. Such a single stage ac-dc converter simulated using MATLAB/SIMULINK at 50-kHz switching frequency
