Flexible Transformers for Switched-Mode Power Supplies

Flexible Transformers for Switched-Mode Power Supplies
 

Flexible transformers consists of a fractionally-rated converter and a slightly modified medium voltage (MV) distribution transformer with additional taps. The converter can be wired to either the primary or the secondary side of the transformer, resulting two different configurations. The proposed device successfully meets the requirements of great performance, long lifetime, high efficiency, and low cost for typical utility assets. 

FKS COILS presents a new line of transformers for SMT assembly --FLEX HV (Flexible Transformer High Voltage). Like the FKS-FLEX series of transformers, these excel because of their flexible capabilities in various applications making them ideally-suited for fast prototyping.

Different circuit configurations enable over 375 transformer solutions and around 125 choke solutions.

Applications include flyback converters, forward converters, push-pull converters, step-up and step-down converters or single-ended primary-inductor converters (SEPIC). With their isolation voltage of 1.5 kVac, these transformers are currently unrivaled on the market.

The newly developed MnZn core material reduces core losses by up to 30 percent as compared with classical products and makes the new SMD transformer an attractive solution for all types of isolated dc-dc converters in industrial and telecommunications applications. 

The working temperature is specified as -40°C to +125°C. Given suitable circuitry, the large package types of the series have a basic isolation for working voltages up to 250Vrms.

Free samples from the new SMD transformer series are now available.
