Applications of motor drives, ranging from automotive traction to more-electric aircraft, have widely varying speed and torque demands. With extensive use of inverter-fed drives, loss minimization techniques for such applications have evolved over the past few decades. Previous work on loss minimization has mainly focused on specific drive components. Component-level loss minimization, however, will...
The use of LC filters between inverter and motor terminals results in undesirable resonant oscillations in motor voltages and currents. Because passive damping methods employ physical resistors to suppress these oscillations, they contribute to additional losses. Lossless active damping methods with virtual resistors have been explored in the literature as a viable alternative. In a typical active...
