New rectifier, dual PFC and inverter product family

Designed for welding, charger and SMPS applications rated from 1.5 to 7kW, a new 3-in-1 solution that integrates three topologies into one flow1 housing, the flowRPI 1 family has been introduced by Vincotech. The flowRPI 1 family combines a rectifier with highly-efficient low-voltage drop diodes, a two legs PFC featuring ultrafast 650V IGBTs and diodes, integrated filtering capacitors and diodes for current sensing via external transformer, and an inverter with H-bridge open emitter topology and optional capacitors into a single module that enables engineers to save design-in time and cost. A special version comes with a PFC featuring IGBTs with higher current ratings for a wider input voltage range. It is rated for applications with Vin = 110 – 220VAC. These carefully selected components provide the best solution for high-frequency, high-efficiency switching. The enhanced layout of the new flowRPI 1 family is more EMC-friendly. With the latest IGBT H5 chip technologies on board, the module delivers ultra-fast switching at ultra-low conduction and switching losses. Given the option of three power stages in a single module, engineers will find it very easy to design highly-compact PCBs. Various power ratings are available in the same flow1 housing with the same pinout, so applications may be scaled up with PCB design remaining intact. This latest generation module covers application power ranges from 1.5 up to 7kW in various steps. The new flowRPI 1 family comes in flow1 12mm and 17mm housings. Press-fit pins and phase-change material are available on request, says the company.
