Advancements in silicon and wide-bandgap (WBG) semiconductors have revolutionized power converters, allowing inverters to operate at frequencies up to several hundred kilohertz, and even megahertz, with substantially reduced dynamic losses.Why do power inverters lose power if switching frequency increases?It is demonstrated that the power losses of power inverter are linearly increased with the rise of switching frequency, which is mainly caused by the switching losses of mosfet chips increment.
Does VSF-hpwm reduce traction inverter power loss?For this reason, the benefit of the VSF-HPWM on the total power loss of a traction inverter is demonstrated through a comparison with the SVPWM over wide speed and torque range. Furthermore, a method of adjusting the location of the clamping period is illustrated. The rest of this paper is organized as follows.
What is the nominal switching frequency of the inverter?The nominal switching frequency of the inverter is 10 KHz. The rest of information, such as the switching energy losses, collector-emitter voltage drop, and thermal parameters, which are necessary to calculate the power losses can be found in the datasheet. Fig. 10. Drivetrain configuration with the control scheme for each converter stage. Table 3.
Does dpwm affect switching loss saving in variable power factor?However, for variable power factor such as in traction applications, the method can't maintain the same switching loss saving because it depends on DPWM with fixed location of the clamping period that is not always aligned with the peak duration of the motor currents.The aim of this study is to address these two issues.
Which traction inverter is best for EV traction?However, as the power factor slightly changes, the switching loss reduction capability reduces drastically making it less attractive for EV traction inverter since the power factor angle of the traction motor is expected to change frequently. Finally, the GPWM and VSF1-SVPWM offer the best compromise between the THD and loss reduction.
What is the voltage and current rating of an inverter module?The module has voltage and current rating of 650 V and 400 A, respectively. The nominal switching frequency of the inverter is 10 KHz. The rest of information, such as the switching energy losses, collector-emitter voltage drop, and thermal parameters, which are necessary to calculate the power losses can be found in the datasheet.
