IC-CAP Power Electronics Modeling

As power modules become smaller, switching frequencies increase and new wide band gap (WBG) technologies enable ever faster edge switch rates, we observe a growing need for accurate device models for the power electronics design community. Advanced models are presented for the following three technologies and device structures:

GaN ASM-HEMT Model, adopted by the CMC

Gallium Nitride (GaN) Advanced SPICE Model for High Electron Mobility Transistors (ASM-HEMT) Model, adopted by the Compact Model Coalition (CMC).

Keysight model for IGBT devices

All 3 of these models have been implemented in Verilog-A, and are available for simulation in Advanced Design System (ADS) 2017. The Si/SiC and IGBT models have been specially formulated for customers who do not have access to device process parameters, a situation that is common in power electronics design labs.

The user interface reflects the major steps that any modeling engineer must undergo.

Power Electronics Modeling

Figure 1. The measured data shown in square markers are well captured by the modeled data shown in solid lines. Various modeling steps are shown on the left. On the right, parameters may be manually tuned using sliders.

There are two groups of customers that will leverage these extractions: circuit designers and modeling engineers. For designers, we present the W8598BP/BT Power Electronics Model Generator (PEMG) Software Bundle for Device Modeling. Designers can leverage extraction flows for all the model types offered: GaN HEMT, Si/SiC PowerMOS, and IGBT. For modeling engineers who want maximum flexibility to customize their flows, we present three IC-CAP add-on packages. These are products summarized in the table below.
