Vincotech unveils flowRPI 1 family of 3-in-1 rectifier, dual PFC, and inverter devices



The flowRPI 1 family integrates three topologies into one flow1 housing

Vincotech, a supplier of module-based solutions for power electronics, announced the release of its flowRPI 1 family, a new 3-in-1 solution that integrates three topologies into one flow1 housing. This module is designed for welding, charger and SMPS applications rated from 1.5 to 7 kW.


The new 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 currrent 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 – 220 VAC. 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 7 kW in various steps.


The new flowRPI 1 family comes in flow1 12 mm and 17 mm housings. Press-fit pins and phase-change material are available on request. These modules will be manufactured in series in early 2016.
