Analysis and Control of Hybrid Boost Converter with Simultaneous AC and DC Outputs

In this paper, a converter architecture which will provide a three-phase ac output and a boosted dc output simultaneously from a dc source in not more than one conversion stage is studied. This circuit known as $\mathbf{3}-\phi$ HBC ($\mathbf{3}-\phi$ hybrid boost converter), is obtained from the traditional dc-dc converter operating in boost mode, where a three phase bridge circuit takes place of control switch. HBC shows immanent shoot-through protection proficiency. Such converter with better multi-output competency and authenticity is befitting the systems with both ac & dc loads in simultaneous mode e.g. PV charging stations, residential and industrial applications, etc. Independent regulation of Both the three-phase ac output and step-up dc output is attainable in case of HBC. For our intent to regulate dc as well as ac output, appropriate PWM control scheme is given in brief. To validate the converter operation, simulation results are demonstrated with resistive and inductive loads and the steady state performance analysis is done.
