UNTERHACHING, Germany -- May 14, 2013

Vincotech, a leading supplier of module-based solutions for power electronics,
has extended its new line of low-inductive power modules with the 3xflowNPC
4w. This latest addition comes in the new wide-body housing and with a higher
power rating. It is well suited for applications such as three-phase solar
inverters ranging up to 200 kW. Its advanced, paralleled NPC design delivers
ultra efficient performance at higher switching frequencies. The 3xflowNPC 4w
also provides asymmetrical inductance with optional regeneration.

All three phases of the Neutral Point Clamped inverter topology are integrated
into this new low-inductive package with a high-power screw interface. The
multilevel NPC topology cuts output filter effort and filter losses by more
than 50 percent, and switching losses by 50 percent.

Rated for 1200 V/600 A, the advanced NPC 3xflowNPC 4w module’s inductance is
asymmetrical. It achieves low turn-off inductance with integrated DC snubber
capacitors and uses parasitic inductance to reduce turn-on losses, so there is
no need for low-inductive busbars. This design and its onboard DC capacitors
extend PWM frequencies beyond 20 kHz, which is unique in this power range.

The low-inductive 3xflowNPC 4w power module is available in the flowSCREW 4w
housing. Samples can be ordered via standard sales channels.
