High-Precision Power Electronics Measurements with Siglent

Requirements and Challenges of Modern Power Electronics

Modern power electronics must meet high standards. Developers face the challenge of designing increasingly efficient, compact, and powerful systems while complying with strict regulations and environmental requirements. Key factors include low energy losses, high switching frequencies, minimal DC ripple, and thermal stability. Additionally, advancing technology requires precise test methods to detect and eliminate unwanted oscillations and the resulting EMC issues early in development. Active components such as microcontrollers and FPGAs require very dynamic power supplies with high power integrity. Therefore, high-precision measurement technology is essential to ensure system quality and reliability while keeping development times under control.

Analyzing Power Supply Disturbances

Accurate ripple and noise measurements on power supplies are critical to ensuring the quality and stability of electronic systems. Siglent offers the SAP4000P Power Rail Probe, which, in combination with 12-bit oscilloscopes, provides an optimal solution for demanding ripple measurements. With a DC offset of ±24 V and a bandwidth of 4 GHz, this solution enables the detection of even the smallest high-frequency disturbances on the power supply rail. This allows developers to identify critical influences and take corrective measures to improve power delivery.

Double-Pulse Test: The Challenge of Power Measurement

A key test method in power electronics is the double-pulse test, which enables the detailed characterization of switching losses in power semiconductors. It is essential for optimizing efficiency and thermal management. High-resolution signal acquisition, low measurement uncertainty, and an efficient test setup are crucial for success.
