Open HW/SW Platform Accelerates Development Of Control Solutions For Power Electronics

Focus:

Developing a controller at the power electronics (PE) or power systems (PS) level requires a great deal of versatility and expertise in various engineering areas. This is especially true for large, high-power applications such as motor drives, active filters, PV inverters, and flexible ac transmission systems (FACTS). Controller development is very time-consuming, laborious and expensive and yet very inflexible if a traditional testbench approach is applied. To cope with these challenges, PERUN Technologies has developed a comprehensive open platform known as the LARA-100. After describing the LARA-100's features, this article explains how this hardware/software platform can be used for controller development, to supplement an existing development platform (with LARA-100 emulating a source or load) or as a combination of these uses. Two case studies are presented to illustrate the first two use scenarios. In the first case study, which illustrates controller development, the LARA-100 is configured as a STATCOM that provides reactive power injection to a power grid. In the second case study, the LARA-100 is configured as a motor load.
