Power Integrations has updated its power supply design software, PI Expert Suite v7.1.4, to support its latest HiperPLC controller IC.

The claim is that the software will speed the design of resonant LLC power supplies with power factor correction (PFC) by eliminating tedious iterative magnetic design.

The tool features the automatic selection of series and parallel resonant element values from user-defined output load requirements and nominal switching frequency. The software also insures zero-voltage switching (ZVS) under all LLC load conditions.

It calculates losses in key power elements of the PFC and LLC power stages and performs PFC boost choke power loss and magnetic field intensity (H) calculations for the PFC choke design.

The new software provides a visualisation tool which graphically illustrates a design’s switching frequency versus output power.

HiperPLC combines PFC and LLC controllers in a single IC, which is designed for high-efficiency offline converters from 200 to 600W.
