Abstract: Silicon carbide (SiC)-based switching devices provide significant performance improvements in many aspects, including lower power dissipation, higher operating temperatures, and faster switching; compared with conventional Si devices, all these features contribute to these devices generating interest in applications for electric traction systems. The topology that is frequently used in these systems is the voltage source inverter (VSI), but the use of SiC devices in the current source inverter topology (CSI), … Show more

“…The sequence of SV-PWM has a large influence on common-mode voltage reduction and may cause bearing currents, especially in high-power machines, as described in [22]. Another interesting aspect of the construction of CSI, shown in [23], is the use of silicon carbide transistors, which allow to increase the frequency of the PWM modulator to tens of kHz and reduce the size of passive elements in the inverter.…”

“…It should be noted that Equations (23) and (24) may be simplified due to the fact that in steady-state, the auxiliary variables u sf1 and u sf2 are approximately equal to 1 and 0 in p.u. In the simplified version of the equations, they take the form:…”

“…For the output voltage control loop, PI controller is enough to regulate the output voltage to the specified value [14], but for the inductor current control loop, the slow response of the PI current controller at the current zero-crossing point causes distortion of the inductor current which leads to increasing the THD of the supply current [15]. Increasing of the THD in the converter circuits, causes higher power losses in all circuit components, further, it can lead to high current stresses and failures of the system insulation and protection [16]. Power quality and performance requirements required to maintain the THD value at the standard values such as IEEE 519-20142 [17], and IEC 61000-3-2 [18], which suggests that in order to improve the circuit P.F, reducing the current stresses and reducing the power losses in the system different parts, THD should be kept at the lowest value with the given standard requirements [17,18].…”

“…At higher switching frequency applications, the multilevel converter topologies have a lower total harmonic distortion (THD) factor than two-level converters [10]. Furthermore, a simple technique is developed in [11] to reduce THD and improve efficiency based on SIC semiconductor power devices.…”
