Sliding Mode Current Controller for the Three Phase Single-stage Ac/dc Buck-boost Converters
نویسندگان
چکیده
This paper presents a sliding mode space vector current modulator for three-phase single stage AC/DC Buck-boost rectifiers. Using this fast and robust control method, this type of converters draw near sinusoidal input currents with high power factor. A Proportional Integral (PI) controller can, then, be adopted to regulate the rectifier output voltage. The references of the sliding mode current controller are sinusoidal waveforms whose amplitude is modulated by this external voltage controller. Simulation and experimental results show the high power factor and low harmonic distortion obtained.

متن کاملSliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency
In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...
