Keysight has introduced advanced power electronics modeling solution to address the growing requirements of electronics designers in the hybrid-electric and electric vehicle (HEV/EV) industry, as well as the solar industries, who want to make their modules smaller, cooler and more efficient by using new wide-bandgap semiconductors in their designs.

The Keysight PD1000A Power Device Measurement System for Advanced Modeling and the W8598BP/BT Power Electronics Model Generator Software are new tools for modeling and simulation of power electronics devices.

In the announcement, Keysight explained: “Vehicle and solar designers nowadays want to leverage some of the newer but more expensive wide-bandgap semiconductor technologies, such as Silicon-Carbide (SiC) and Gallium-Nitride (GaN). Wide-bandgap (WBG) semiconductor technology enables power-converter designs with faster switching speeds due to smaller intrinsic device capacitances. With higher switching speeds, the supporting circuitry can be made much smaller, resulting in a smaller module footprint that is also lighter and cooler.”

Although these benefits are highly desirable in both vehicle and solar inverter designs, Keysight says that the fast edge rates and higher switching speeds lead to new concerns in reliability, safety, and electromagnetic emissions.

Transient-induced electromagnetic (EM) noise can lead to EMI non-compliance and unexpected inrush currents can lead to reliability problems, both resulting in extra design cycles and/or long-term quality issues.

Keysight contends that its solution is designed to solve these problems and the company is working with designers in the HEV/EV power-conversion market to help them transition smoothly towards the use of wide-bandgap devices in their designs.

The test suite, which consists of DC I-V and capacitance curve tracing, S-parameter, and double-pulse test hardware, takes measurements from actual wide-bandgap devices and uses advanced modeling software to build sophisticated wide-bandgap device models exclusive to Keysight.

According to the company, these models can then be used in its Advanced Design System (ADS) software to simulate and analyze the effects of the high-frequency components on the reliability and EMI performance of the design. With the critical insights gained from the simulations, designs are made robust in the first prototype, thus saving unnecessary design cycles, time and money.
