Datasheet

Agilent Technologies has developed a power device capacitance analyser that automatically characterises power device junction capacitances using real operating voltages. With the increasing use of power devices fabricated from emerging materials like SiC and GaN, switching power supplies are now operating at increasingly higher frequencies.

As a result, accurate device capacitance characterisation is more important than ever. With its ability to accurately and automatically evaluate all input, output and reverse transfer power device capacitance at high bias voltages, Agilent’s B5170A Power Device Capacitance Analyser is well equipped to address this task.

The analyser provides a complete solution for measuring and evaluating all parameters for high-frequency switching power supplies.

Measurement capabilities include three terminal capacitances (C_iss, C_oss and C_rss) with high-voltage bias (+/-3 kV), gate resistance, and accurate leakage current and breakdown voltage by complementing curve-tracer-type test equipment that evaluates only coarse IV characteristics.

A uniquely designed intuitive graphical user interface makes it easy for even a novice user to automatically measure all capacitances under a wide range of operating voltages.

Such capabilities make the B1507A ideal for helping power electronics circuit designers select the optimal devices for their power electronic circuits and for power electronics manufacturers maximising product value and performance by revealing detailed device characteristics.
