FET-Jet Calculator online power design tool launched

In order to identify the optimal UnitedSiC device for their power design, users select their application function and topology, enter their design parameter details, and the tool automatically calculates switch current, efficiency, and losses, categorised by conduction, turn-on, and turn-off contributions. Operating temperature and heatsink rating are included as inputs, to show expected operating junction temperatures.

Users can explore the effect of changing conduction modes in the various topologies by varying storage inductor and switching frequency values. Additionally, single or paralleled devices can be selected to show relative overall performance of devices with various current ratings.

The tool warns if a selection is not appropriate, such as when voltage rating is insufficient for the conditions and topology chosen, helping the user to rapidly arrive at a viable solution.

All UnitedSiC FETs and Schottky diodes can be selected from sortable tables, which include devices in TO-220, TO-247, TO-247/4L, DFN8x8 packages and the recently launched Gen 4 750V devices.

Anup Bhalla, VP Engineering at UnitedSiC, commented: “Selecting the right device in the right power topology shouldn’t be a barrier to power designers considering the switch to SiC. This is why we built the FET-Jet Calculator.

“For engineers working with SiC for the first time, or those looking for the best SiC device to fit evolving designs, the calculator is a quick and easy way to evaluate UnitedSiC FETs in a variety of power topologies - speeding up R&D by avoiding any wasted time creating advanced simulations for inappropriate devices. Just a few clicks put you on the right heading to arrive at an optimum design.”
