Measurement technology that enhances not only measurement accuracy but also automation and analysis efficiency is important.

At the 2026 Power Electronics Conference held from July 13 to 16, Teledyne LeCroy, a company specializing in measurement equipment, showcased the latest measurement solutions for analyzing power semiconductors and motor drive systems.

Managing Director Oh Chang-hoon, who is in charge of technical support at the conference, expressed confidence in measurement automation and high-current analysis technology, which have emerged as key challenges in the field of next-generation power electronics.


The first thing Executive Director Oh Chang-hoon emphasized was the Double Pulse Test automation solution.

The double pulse test is considered a widely used test method for evaluating the switching characteristics of next-generation power semiconductors, such as SiC (silicon carbide) and GaN (gallium nitride).

He explained, “Basically, it consists of an oscilloscope, isolation probe, differential probe, Rogowski, and current probe, and combines a pulse generator and power supply to operate as a single integrated system.”

In particular, it is characterized by the fact that the measurement process proceeds automatically once the user simply inputs the test conditions.

When the test is run, the system pulse widthIt automatically adjusts and collects data, loads measurement results into an interface, and automatically generates a final report.

This means that the repetitive measurement process previously performed manually by researchers or engineers can be significantly reduced.

"One of the most important elements is oscilloscope software," said Executive Director Oh Chang-hoon. "We have combined automation functions based on a power device solution that automatically analyzes the switching characteristics of SiC and GaN-based power systems."

The second solution introduced is the Motor Drive Analysis system.

It is designed to more efficiently analyze the voltage, current, and power characteristics of motor drive systems used in electric vehicles and industrial equipment.

This solution measures the voltage and current of each phase simultaneously based on an 8-channel oscilloscope.

The measured data is quantified and provided in the form of a table on the screen, allowing users to immediately check the relevant power values and trends simply by selecting the desired item.

In particular, it allows you to grasp changes in measurement values for each cycle at a glance, aiding in motor drive performance analysis and system optimization.

For measurements, three differential probes for three-phase voltage analysis and three current probes for current measurement are basically used.

This allows for the precise analysis of various electrical characteristics occurring in a motor driving environment.

Along with this, Teledyne LeCroy also unveiled a new product, the 1,000A current probe, at the conference.

This product is designed to measure high-current environments, such as inverter outputs, and is a solution to meet the increasing demand for high-current measurement driven by the recent proliferation of electric vehicles and high-capacity power conversion devices.He was introduced as Sean.

Executive Director Oh Chang-hoon stated, “As next-generation power semiconductors and motor control technologies are rapidly developing, establishing a more sophisticated and efficient measurement environment determines the competitiveness of the power electronics industry.”
