    Inherent current imbalances are often present in electric distribution systems due to the increase of singlephase generation in the form of renewables and the existence of single-phase loads. The continued expansion of non-linear load usage is also increasing the levels of harmonics through the power transformers servicing these distribution systems. The issues that arise from these operating conditions are widely known and standard solutions used by utilities are as well. However, they are often bulky and do not provide a level of control or versatility appropriate for these challenges. This paper gives an overview of many of the problems that are faced on distribution systems and how an active shunt compensator may be used to mitigate or eliminate them.

    The analysis of a shoot-through-proof converter topology designed to eliminate the need for a dead time between switching transitions is presented. Shoot-through-proof is done by splitting each leg of a normal converter and inserting an inductor to limit the current during transitions. Matlab/Simulink™ simulations based on a 10-kVA laboratory test setup, which was built to validate the proposed ideas, are used to evaluate the system performance. In particular, simulations were used to predict losses associated with the topology and reduce the harmonics injected by the converter. The control system was implemented in a TMS320F28335 DSP, and the results of both the simulations and prototype testing showed very good agreement.
