Development of power electronic devices requires multi -disciplined engineering activities. These cover the thermal, electrical and software design. Due to this design complexity rapid prototyping methods and model-based design are becoming more and more important in the R&D projects in this field. In case of the multi-level inverter based drives the strict reliability requirements make the aforementioned new approaches more attractive. This article is the first part of the series which introduces the application of the model based design and Hardware-in-the-Loop (HIL) tools through the modeling of a Cellular H-Bridge inverter (CHB). This article focuses on the power electronic system modeling and verification. The model of the CHB is implemented and verified in Matlab.

Current Carrying Capability

A transconductance-like behavior similar to that of junction semiconductor devices is observed in photonically excited wide bandgap (WBG) semi-insulating material without a junction. This property offers the possibility of power electronic devices capable of virtually unlimited voltage and current carrying capability due to intrinsic electrical isolation of the controlling voltage from the switched high voltage. A proof of concept experiment demonstrated the transconductance-like property in burst mode switching to >16 kV, 50% duty cycle, and 75 kHz. Our eventual goal is to combine the light source, optics and the WBG material to form a compact module that is functionally equivalent to junction power electronic devices. In this paper, we present the background, our generalized approach for implementing photoconductive switching for potential applications to high repetition rate (>50 kHz), high voltage (>15 kV) power switching, our associated material measurements, and our path forward to multi-10s of ampere devices.

ABSTRACTSiC power switching devices have demonstrated performance figures of merit far beyond the silicon theoretical limits, but much work remains before commercial production will be feasible. A significant fraction of the remaining work centers on materials science issues. This paper reviews the current status of unipolar power switching devices in SiC and identifies the major technological and material science barriers that need to be overcome.

Internal Structures

With the development of China’s electric power, power electronics devices such as insulated-gate bipolar transistors (IGBTs) have been widely used in the field of high voltages and large currents. However, the currents in these power electronic devices are transient. For example, the uneven currents and internal chip currents overshoot, which may occur when turning on and off, and could have a great impact on the device. In order to study the reliability of these power electronics devices, this paper proposes a miniature printed circuit board (PCB) Rogowski coil that measures the current of these power electronics devices without changing their internal structures, which provides a reference for the subsequent reliability of their designs.

Further Development

Measurements of medium and high voltages in a power grid are normally performed with large and bulky voltage transformers or capacitive dividers. Besides installation problems, these devices operate in a relatively narrow frequency band, which limits their usability in modern systems that are saturated with power electronic devices. A sensor that can be installed directly on a wire and can operate without a galvanic connection to the ground may be used as an alternative voltage measurement device. This type of voltage sensor can complement current sensors installed on a wire, forming a complete power acquisition system. This paper presents such a sensor. Our sensor is built using two dielectric elements with different permeability coefficients. A finite element method simulation is used to estimate the parameters of a constructed sensor. Besides simulations, a laboratory model of a sensor was built and tested in a medium-voltage substation. Our results provide a proof of concept for the presented sensor. Some errors in voltage reconstruction have been traced to an oversimplified data acquisition and transmission system, which has to be improved during the further development of the sensor.
