A PSCAD simulation on integration of multi-level converters with DC-DC converter for AC drive applications
Bidirectional dc-dc converter allows transfer of energy between two dc buses. As renewable energy systems are fluctuating in nature we use a energy storage system, bidirectional dc-dc converter allows exchange of energy between storage system and the system. Bidirectional dc-dc boost converter can be utilized to step-up voltage level in renewable energy sources which reduces the ripple content in output. This paper focuses on Integration of Multilevel converter with bidirectional dc-dc converter by connecting to a common DC bus to feed AC motor drives. multilevel converters has low ripple content, can generate near sinusoidal voltages with only fundamental switching which is very suitable for large motor drives this paper focuses on low frequency, high power applications of AC motor drives by employing a Hysteresis current control.
