Indiana University-Purdue University Indianapolis (IUPUI) / This thesis proposes a family of non-isolated bidirectional converter in order to
interface dc and ac variables. Such power electronics solutions guarantee: (i) bidirectional
power flow between dc and ac converter sides, (ii) independent control in both
converter sides, (iii) high level of integration with a reduction of one power switch
and its drive circuits, (iv) implementation of two functions by using a unique power
conversion stage and (v) reduction of the capacitor losses. Despite proposing new
power converter solutions, this thesis presents an analysis of the converters in terms
of pulse-width-modulation (PWM) strategy, dc-link capacitor variables, and suitable
a control approach.
Solutions for single-phase, three-phase and three-phase four-wire systems are proposed
by employing a converter leg with three switches. A possible application of
this converter is in Vehicle-to-Grid (V2G) systems and interfacing dc microgrid with
a utility grid.
In addition to the new power electronics converters proposed in this thesis, an
experimental setup has been developed for validation of the simulated outcomes. The
proof-of-concept experimental setup is constituted by: DSP, Drivers & Integrating
Board, Power Supply and, Power Converter & Heat-Sink .
