<p>In recent years, switch-mode power electronic converters have gained considerable popularity</p>
<p>because of their compact size and high switching frequencies. This makes them</p>
<p>suitable for power processing in various applications, including photovoltaic systems and</p>
<p>electric vehicles. However, their high switching frequency capabilities have a drawback. A</p>
<p>high-frequency common-mode voltage coupled with the switching of the power converters</p>
<p>excites the parasitic capacitances of the system. It leads to the flow of common-mode current.</p>
<p>Since the common-mode current flows through an unintended path, it can potentially</p>
<p>interfere with the performance of system components. Passive filters can be used to mitigate</p>
<p>common-mode currents. Using a common-mode inductor in conjunction with strategically</p>
<p>placed capacitors makes it possible to limit the flow of common-mode current.</p>
<p><br></p>
<p>As part of this work, passive mitigation of common-mode current will be investigated in</p>
<p>a variable frequency drive system. In this regard, the process of designing a three-phase ac</p>
<p>common-mode inductor is explained. As a first step, a mitigation strategy is proposed and</p>
<p>described. Next, the issue of self-capacitance of the inductor is discussed. Afterwards, the</p>
<p>ac common-mode inductor is designed using a multi-objective optimization-based approach.</p>
<p>Following this are the design results, concluding the dissertation.</p>
