The performance of modern wide bandgap semiconductors cannot be fully exploited in inverters for motor drive applications, since faster switching is not possible due to the high du/dt causing overvoltages due to reflections on cables and EMI issues. Classical LC filters are also not suitable, as these limit power density. This situation calls for an active du/dt filter implementing intelligent switching transitions of the power semiconductors to ensure high efficiency and low du/dt at the output simultaneously. Theoretically, the modulation scheme can deliver ideal smooth transitions. However, in practical setups non-idealities cause severe oscillations of the resonant tank. This paper studies the origin of this oscillation and proposes a compensation method to successfully reduce the undesired oscillation.

This paper proposes an advanced ripple suppression scheme by controlling the bus voltage complementary with the dual active bridge (DAB) converters under extended phase shift (EPS) control without uncontrollable intervals. The existing differentiated capacitance design is based on the DAB converter under single phase shift (SPS) control, which has a limitation in parameter optimization. Meanwhile, to minimize the current stress of the DAB converters, an optimization method is designed, which considers the fluctuation of output voltage for accurate parameter selection. At the same time, this method achieves zero voltage soft (ZVS) in the DAB converters. The input-parallel output-series (IPOS) structure is adopted as the main circuit. Simulation results are provided to verify the effectiveness of the proposed scheme.

This paper analyzes the possible zero clamping region of a three-level inverter to reduce switching loss and how to select positive, negative, and zero clamping in discontinuous PWM (DPWM). Based on these analyses, carrier-based minimum-loss DPWM (MLDPWM) is proposed for the three-level inverters within all ranges of power factor angle and high modulation index. Under consideration of not only positive and negative clamping but also zero clamping, the proposed method could increase the clamping region furthermore in the vicinity of a peak current at a lower power factor and higher modulation index. Thus, the switching loss can be minimized by reducing the number of switching near the peak current even under low power factor operation. The performance of the proposed method is compared with that of the conventional DPWM method in the aspect of switching loss function (SLF). Lastly, the effectiveness of the proposed method is verified by simulation and experimental results.

To increase efficiency and reduce material consumption, the increased use of wide-bandgap (WBG) power semiconductor devices becomes indispensable. However, challenges such as the accelerated aging of insulation materials have so far prevented exploiting the full potential of this technology. This paper provides an overview of experiments that can be performed to test insulation systems for their resilience with respect to fast switching transients. To this end, capacitive and inductive specimens are considered. Firstly, the test bench is briefly introduced. Secondly, measurements are performed with standardized twisted pair of enameled wire specimens. The lifetimes at two different voltage slopes are compared, the effect of a consistent discharge at steep voltage slopes is analyzed and the influence of a partial discharge (PD) resistant additive in the enamel is considered. Then, single-tooth coil windings with and without a PD-resistant additive in the enamel are investigated and the influence of an optimized winding configuration demonstrated.

In this paper, an improved capacitor voltages balancing control for five-level hybrid flying-capacitor (5L-HFC) inverters is proposed. The 5L-HFC inverter has advantages of having lower voltage stresses of active switches comparing to the five-level active neutral-point-clamped (5L-ANPC) inverter. The 5L-HFC inverter requires either auxiliary balancing circuits or a control algorithm utilizing phase-shifted PWM (PSPWM) to achieve capacitor voltage balancing. However, the former method requires the additional devices and the latter incurs worse THD of line-to-line voltage. In this paper, thus, a novel capacitor voltage balancing control method with better THD and without auxiliary circuits for the 5L-HFC inverter by controlling the duty ratios and selecting the redundant states based on COPWM. The proposed method has been verified through simulation result at various conditions.

The main objective of this paper is to optimize the overall power losses of a traction inverter operating at a DC-link voltage of 400V by using a discrete 650V Si-IGBT and freewheeling diode and a 650V SiC-MOSFET in parallel. The study proposes a new approach to decouple the SiC-MOSFET half bridge and the IGBT/Si-Diode half bridge from each other using a small additional inductance. This approach reduces the turn-on losses of the SiC-MOSFET and turn-off losses of the Si-Diode, resulting in lower overall losses in the hybrid-switch inverter compared to a non-decoupled configuration. The system losses of the hybrid-switch inverter are simulated and validated through both a double pulse test setup and an inverter test rig.

GaN HEMT devices feature the advantages of high frequency, high efficiency, and high power density for power converters due to their excellent performances. At high frequencies, GaN is highly sensitive to parasitic parameters, which can lead to voltage and current overshoot, electromagnetic interference, additional power losses, and even device failure. These issues are very important for the power devices and the whole power conversion systems. However, there is a lack of a comprehensive and in-depth overview of GaN technology in high frequency applications. This paper focuses on the issues of driver circuit and power loop design, the parallel technology, the short-circuit protection technology, which is helpful for better use of GaN devices in high frequency applications.

To achieve high-performance control of the brushless direct current (BLDC) motors, a direct DC-link current control (DDLCC) is introduced and compared with the direct torque control (DTC) method. Similar to the DTC method, the proposed DDLCC method has a fast transient response; nonetheless, it comes with higher reliability, cost-effectiveness, and lower torque ripple. Although this method provides average torque ripples lower than those of the DTC method, the commutation torque ripple is higher. A four-level hysteresis controller is utilized to distinguish the commutations, and then, the commutation torque ripple is suppressed by applying appropriate voltage vectors. These vectors provide similar fall time and rise time for both commutated currents and suppress commutation torque ripple. The results verify these appropriate voltage vectors guarantee the stable performance of the BLDC motor as well as commutation torque ripple reduction compared to the conventional DTC method.

Wound-rotor synchronous starter/generator (WSSG) contains lots of low-order harmonics, caused by the inverter, on the stator side of the main generator (MG) during the starting stage, which would affect the performance of sensorless starting control with high-frequency injection. To solve this problem, a harmonic detection, based on synchronous rotating frame transformations (SFT), and compensation method is presented first to suppress the 5th and 7th harmonic current during their generation. Besides, a second-order generalized integrator (SOGI) is applied to further reduce the influence of harmonics on the observer of high-frequency response signals, the source and the transmission path suppression of the low-order harmonics are combined in this paper, and the simulation results show that the proposed strategy can effectively suppress the low-order harmonics and reduce the rotor position estimation error caused by them.

In recent years, the realization of an energy system that uses renewable energy as the main power source is being considered toward carbon neutrality. Authors are developing a low-cost, highly functional, and versatile Universal Smart Power Module (USPM) to adapt to various power electronics system. In this paper, a power conversion system using multiple USPMs is verified as a Grid-Tied system for PV generation, which consists of a USPM master controller, USPM slave inverter unit, USPM slave chopper1 unit, USPM slave chopper2 unit and equipment housing. Three phase grid-tied inverter was experimentally verified to confirm the USPM controller capability. A demonstration was carried out with a PV simulator, an energy storage battery, and a utility voltage simulator. Slave USPM controller controls its own USPM module. All the slave controllers communicate with the master controller via CAN network to operate the sequence control. Basic function of the proposed system was confirmed.
