“…The variation of phase resistance is ignored in most of the previous flux linkage measurement methods, which leads to the estimated position error. According to (1) and (2), the relationship between the measured flux linkage error and estimated resistance error is Equation 21indicates the sign of the flux linkage error is opposite to that of the resistance error, and its value is related to the resistance error and the integral of current.

The accuracy of flux linkage measurement is significantly important for a number of sensorless control methods for switched reluctance motor (SRM). This study proposes a novel flux linkage measurement circuit with the automated resistance correction, which comprises only circuit components. During the SRM sensorless operation, the dependence of resistance on temperature leads to the errors in flux linkage measurement and position estimation. The developed scheme is based on the zero-crossing property which asserts that the flux linkage and current pass through zero simultaneously. Hence, the flux linkage error captured at the time when the current falls to zero represents the resistance error and is used for resistance correction. The proposed circuit has been successfully implemented and tested on a sensorless SRM system. Experiment results indicate that the proposed system in sensorless control can be operated stably at different load torques and at the condition of given speed mutation and load mutation, and the speed range in steady state with rated load torque is 0-160 r/min. The overall estimated position error remains within an acceptable margin of 2%. Hence, it significantly improves the sensorless position estimation and thus SRM performance.

This paper introduces a gallium nitride (GaN) high electron mobility transistor (HEMT)-based matrix converter for motor friendly drive systems. A fast switching characteristic of the GaN devices causes high dv/dt. This increases the importance of noise immunity and the reduction of parasitic components in system design. In addition, the high dv/dt in motor drive systems leads to voltage spike at a motor input terminal and leakage current through a motor chassis. Accordingly, a gate drive circuit consists of devices with a high common mode transient immunity. A printed circuit board was designed to minimize parasitic inductance, which was analyzed by performing simulations. To mitigate the dv/dt of the voltage applied to the motor and the leakage current, a dv/dt filter and a sine-wave filter were utilized as an output filter of the matrix converter. The effectiveness of each filter was verified by driving an induction motor.

“…With the imminent electrification of many of our current transport systems, there is a need for high performance power switching electronics for uses such as electric/hybrid vehicles, grid scale energy storage, industrial machinery control, and military systems. [1][2][3][4][5][6][7][8] In such cases, power electronics are responsible for the controlled transmission and conversion of electric energy for the appropriate end-use. Electronic switching devices based on materials such as Ga 2 O 3 , GaN, and SiC have great potential for these uses.…”

The effects of bilayer field plates with various dielectric (SiO 2 /SiN x , Al 2 O 3 / SiN x , HfO 2 / SiN x) on Ga 2 O 3 Schottky rectifier performance were investigated. The rectifiers were fabricated on 10 μm thick, Si doped (n = 2.8 × 10 16 cm −3) β-Ga 2 O 3 epitaxial layers grown by hydride vapor phase epitaxy on Ga 2 O 3 Sn-doped substrates (n = 4.8 × 10 18 cm −3) grown by edge-defined, film-fed growth. Temperature-dependent forward current-voltage characteristics were used to extract the average Schottky barrier height of 1.14 eV ± 0.03 eV for Ni, average ideality factor of 1.02 ± 0.02, and the Richardson's constant of 48.1 A/cm 2 K 2. The reverse breakdown and leakage current were the two characteristics predominantly affected by the field plate dielectrics. The highest reverse breakdown reached was 730 V for rectifiers with Al 2 O 3 / SiN x , which was significantly higher than 562 V and 401 V for rectifiers with SiO 2 / SiN x and HfO 2 / SiN x , respectively. The on-resistance ranged from 3.8-5.0 × 10 −3-cm 2 , which was dependent on diode size, with diameters from 50 to 200 μm. This led to a power figure-of-merit (V B 2 /R ON) of 140 MW-cm 2. Design of the field plate is crucial in determining where reverse breakdown occurs.
