Keysight Technologies 1500 A and 10 kV IGBT Characterization Using the Keysight B1505A Power Device Analyzer/Curve Tracer
■Introduction
▲The Keysight Technologies, Inc. B1505A Power Device Analyzer/Curve Tracer is a powerful tool for measuring and characterizing devices such as insulation gate bipolar transistors (IGBTs). The B1505A’s wide measurement range (1500 A and 10 kV) and advanced features combine to provide an efficient power device measurement solution.
▲The B1505A supports several new external modules that greatly improve its measurement range. These include: an ultra high current unit (UHCU) with a maximum output of 1500 A, a high voltage medium current unit (HVMCU) with a maximum output range of 2.5 A/2200 V and an ultra high voltage unit (UHVU) with a maximum output of 10 kV. These capabilities provide state of the art accuracy, flexibility and ease-of-use for characterizing high power devices such as IGBTs.
▲With its improved measurement range the B1505A can measure the majority of power devices as shown in Figure 1. This figure shows the voltage versus current output ranges of typical B1505A modules for high power applications.
▲Both the UHCU and HVMCU modules possess a 10 μs high-power pulsing capability that allows more precise measurements by eliminating device self heating effects.
▲The B1505A can also perform accurate capacitance versus voltage (CV) measurement at up to 3 kV of DC bias. The B1505A makes it easy to directly measure an IGBT’s capacitance parameters.
▲EasyEXPERT is a GUI-based software resident on the B1505A that supports interactive and real time sweep control in its curve tracer mode. Easy EXPERT supports the automatic extraction of IGBT parameters, which eliminates tedious manual post-measurement calculations.
▲These features make the B1505A a powerful replacement for traditional curve-tracers and provide the user with both improved test efficiency and measurement accuracy.
▲This application note explains how to use the B1505A to measure typical DC parameters of IGBTs.
