APPLICATION NOTE: Measuring Power Supply Switching Loss with an Oscilloscope


Losses due to dissipation in switching devices such as MOSFET's and IGBT's contribute significantly to the overall losses in switch mode power supplies. This application note explains how to measure switching loss and conduction loss in power supply switches using an oscilloscope equipped with a current probe and differential voltage probe. It covers both manual and automated techniques, along with guidance on making connections.

 2. Signal Sources & Analysers

APPLICATION NOTE: Double Pulse Test with the Tektronix AFG31000 Arbitrary Function Generator


Semiconductor materials used in power electronics are transitioning from silicon to wide bandgap semiconductors such as silicon carbide (SiC) and gallium nitride (GaN) due to their superior performance in automotive and industrial applications. However, minimizing switch losses continues to be a major challenge for power device engineers. These designs must be rigorously measured to ensure compliance.

Double Pulse Testing is the standard method for measuring the switching parameters of MOSFETs or IGBT power devices.

APPLICATION NOTE: Testing Laser Diode Modules and VCSELs with the 2601B-PULSE System SourceMeter® Instrument and KickStart Instrument Control Software


Laser diodes (LDs) and VCSELs (Vertical Cavity Surface Emitting Lasers) are the primary components used in optical communications, spectroscopy, 3D sensing and imaging, and a host of other important applications. As the demand for these applications grows, so does the need for the basic components themselves. This demand requires greater emphasis on developing accurate, cost-effective test strategies.

TECHNICAL BRIEF: Evolving Materials and Testing for Emerging Generations of Power Electronics Design


Transitioning from silicon to wide bandgap semiconductors such as silicon carbide and gallium nitride means that power module designs can be physically smaller than what came before, while also increasing MOSFET switching speed and energy efficiency. As competitive pressures make these design parameters more critical, design engineers must reevaluate their approaches to validation and testing.
