Abstract:
This seminar report introduces new hybrid converter topologies which can supply
simultaneously AC as well as DC from a single DC source. The new Hybrid Con
verter is derived from the single switch controlled Boost and Buck-Boost converter
by replacing the controlled switch with voltage source inverter (VSI). This new hy
brid converter has the advantages like reduced number of switches as compared with
conventional design having separate converter for supplying AC and DC loads, pro
vide DC and AC outputs with an increased reliability, resulting from the inherent
shoot through protection in the inverter stage. For controlling switches PWM con
trol, based upon unipolar Sine-PWM is described. Simulink model is used to validate
the operation of the converter. The proposed Converter can supply DC and AC loads
at 190 V and 48 V (rms) respectively from a 48 V DC source.
