The PI Expert Suite v7.1.4 power supply design software supports the HiperPLC controller IC, which combines PFC and LLC controllers. The tool features the automatic selection of series and parallel resonant element values from user-defined output load requirements and nominal switching frequency.
Performing PFC boost choke power loss and magnetic field intensity calculations for the PFC choke design, the software also ensures zero-voltage switching under all LLC load conditions and automatically calculates losses in key power elements of the PFC and LLC power stages. HiperPLC targets high-efficiency offline converters from 200 to 600 W and minimizes the cost of magnetic components and high-voltage bulk storage capacitors by synchronizing the PFC and LLC converter stages.
