flow 0B housing - the compact cost cutter
Vincotech has unveiled the new flow 0B housing sized for small power applications. It is a smaller version of the flow 0 housing, a popular product that has proven its merits in countless applications. This compact alternative is designed to meet the demands of smaller power embedded drives and frequency inverters.
The first of the two debut topologies in the flow 0B housing consists of a PIM + PFC and is called flowCIP 0B. Equipped with a single-phase input rectifier, a PFC booster and a three-phase inverter, it uses high-speed 650 V IGBTs for the PFC. A DC capacitor and an NTC are integrated. The flowCIP 0B module rated for the highest current features a PFC circuit based on a nominal chip current of 15 A and an inverter section equipped with 10 A components. Smaller versions are also available to cover a wide power range.
The other topology is called flowPACK 0B. This standard inverter topology with 6 IGBTs and freewheeling diodes is available with 1200 V and 600 V ratings. The 600 V variant covers currents ranging from 6 A to 30 A; the 1200 V variant comes with currents ratings between 4 A and 15 A.
