Transformer performance isn’t constant—it shifts depending on the load. At light loads, core (iron) losses dominate. As the load increases, copper (winding) losses grow more significant. The point where these two losses balance marks the peak efficiency of the transformer.
But identifying this peak isn’t always straightforward.
In this webinar, we’ll walk through the interaction between core and copper losses and how they shape overall efficiency across load levels. Then, we’ll show you how to use electromagnetic simulation to analyze and visualize this behavior—without relying on guesswork or overly simplified models.
Using the EMWORKS EMAG module, we’ll simulate a real transformer to extract both types of losses under varying load conditions. From this, we’ll generate the full efficiency curve and pinpoint the load level where efficiency is maximized.
Whether you’re optimizing transformer designs or troubleshooting existing systems, this session will offer a practical, simulation-driven approach to improving efficiency where it matters most.
