The Evolution of PCB Electronic Transformers

In the last three decades, electronic products have advanced towards high frequency, high power, low loss, and high cost performance. This shift has significantly impacted the market for traditional EI and C core electronic transformers.

Transition to Planar Transformers

One of the most significant innovations in the industry is the move from three-dimensional transformers to planar transformers. Planar transformers have reduced volume and weight by up to 80% compared to traditional models.

Chip Transformers for Height Reduction

Another notable advancement is the widespread adoption of chip transformers, which significantly decrease height and achieve a nearly flat design. These transformers are ideal for low-voltage, high-current power supplies with currents exceeding 100A.

PCBA Processing Structure

In PCBA processing, the conventional approach of multiple windings with a single magnetic core is being replaced by a structure that typically involves one primary winding with multiple magnetic cores.

Latest Developments

Recent innovations have led to the creation of a product range from 5W to 20kW, operating at frequencies between 20kHz to 2MHz, with exceptional power efficiency of up to 98%.
