REDEXPERT loss simulation

Find the best inductor!

REDEXPERT has the world’s most accurate AC loss model, which even includes the DC-bias current. With dedicated DC-DC topologies or the generic loss simulator, you can accurately determine the AC and DC losses for your converter. The model includes the core material, shape and winding structure of the inductor. REDEXPERT recommends suitable inductors and allows you to add more filters to find the best inductor for your application.

Comments

With effect 7th January 2010 the so-called standby regulation came into force within the European Union. Reducing the power consumption until 2020 by 75% in the standby mode is the aim of this regulation. Due to that regulation electrical home appliance, communication and office equipment aren’t allowed to spend more than 2 Watt in the standby mode. For devices which are simply reactivated only 1 Watt is allowed. From 2014 on the values will reduce further on.
For those standby applications SMPS are needed that are compact and efficient but don’t exceed the requested consumption either. The high voltage version of the power inductors WE-PD2 is especially designed for such applications. A special layout combined with a complex test setup guarantees the requested withstand voltage of the rectified supply voltage of 400 VDC.
