Three-Level Topology for Solar Applications
Vincotech announced the release of a new line of three-level power modules engineered to achieve highest efficiency for single-phase solar inverters, even at reactive power. Packaged in the most compact flow 1 housing, flowPACK 1 H6.5 combines excellent performance with remarkable cost efficiency.
Size and cost are key concerns for single-phase solar inverters. On top of that, they demand a level of efficiency that the conventional H-bridge topology cannot deliver in freewheeling mode. They need a solution with a dynamic short in the output that enables energy to circulate without losses, and without charging back the input supply.
The flowPACK 1 H6.5 is designed with size, cost and efficiency in mind, making it solution of choice for single-phase solar inverters. Compared with the patented Heric inverter the flowPACK 1 H6.5 offers superior efficiency from 4kHz to 50kHz. The higher the switching frequency, the larger the efficiency advantage for the flowPACK 1 H6.5.
The new full-bridge flowPACK 1 H6.5 module comes in a compact, low inductive flow 1 housing and covers 3- to 6-kW applications ranging up to 50kHz. Samples may be sourced on demand beginning July 2016.
