What is a Transient Response Test and what is required to run one?

A Transient Response Test (AKA: Dynamic Load Test) determines how quickly a voltage regulator can respond to a sudden change in Current.  The electronic loads must be programmable to handle the following settings.

Current setting 1 (L1) and Current setting 2 (L2), dwell time (t1 and t2) at each current or duty cycle (DC%), Slew rate for Rising (SR1) and falling edges (SR2).

The below example is for a DC-DC converter rated for 3.3V and 12Amps the Dynamic load is set for 10% to 90% of the maximum rated current for the voltage regulator.

The Chroma 63600 DC Electronic Loads have the Dynamic Load programmability up to frequencies of 20KHz and have the added feature to do Sweep Dynamic Loading which adds the ability to sweep the frequency while running the Transient Load Test.

How to Use RF Impedance Measurements to Ensure the Quality of Miniaturized Power Inductors

Most high-frequency and miniaturized power inductors are metal molding-type inductors. The magnetic metal powder surfaces are usually treated with an oxide layer to reduce eddy current losses at high frequencies, enhancing the usable frequency range and reducing losses and temperature rising. However, users typically cannot determine the particle size of the magnetic material and the integrity of the oxide layer after molding and sintering through visual inspection alone.

Leveraging Certificate Management Tools for Comprehensive EVSE Plug & Charge (PnC) Testing

Chroma’s PowerPro 5 software, part of its comprehensive EV test system solution, features a Certificate Management Tool that allows users to load specific certificate files (*.p12, *.pem). Using designated OEM agreements and contract certificates, the software automatically performs public/private key encryption and decryption during the test to achieve the handshake and payment processes required for ISO 15118 PnC testing.
