Improved Hybrid Converter with Simultaneous DC and AC Outputs
Sarath Prasad K S, T Valsalan, Dr. P Vijayakumar
Abstract: This Paper introduces new hybrid converter topologies which can supply simultaneously AC as well as DCfrom a single DC source. The new Hybrid Converter is derived from the single switch controlled Boost converter by replacing the controlled switch with voltage source inverter (VSI). This new hybrid converter has the advantages like reduced number of switches as compared with conventional design and provides DC as well as AC outputs with an increased reliability resulting from the inherent shoot through protection in the inverter stage. For controlling switches, PWM control based upon unipolar Sine-PWM is described. Simulink model is used to validate the operation of the converter. The proposed Converter can supplyDC and AC loads at 220 V and 230V (rms) respectively from a 12V DC source. . A 50 W laboratoryprototype is used to validate the operation of the converter.
