300A, Three-Level NPC Module with Integrated Snubber Capacitors for UPS and Solar

Vincotech introduced its new three-level NPC module, the flowNPC 2, that the company says helps you get the most out of your solar inverter. The integrated on-board capacitors reduce the voltage over-shoot by 40%, thereby enabling higher dc-link voltages and smaller passive components.

The company optimized the chipset or the new flowNPC 2 module to enhance efficiency at real power while preserving its reactive power capability across a wide range.

The module targets frequencies above 16kHz, and Vincotech says that the new product facilitates the design of compact and light multi-string inverters up to 125kVA. Vincotech designed the flowNPC 2 module for uninterruptible power supplies and solar. Enhanced efficiency maximizes return on investment, and press-fit pins and pre-applied TIM drive down manufacturing costs, according to the company.

The module features three-level neutral-point, clamped topology. The device integrates snubber capacitors and employs the latest chip technology from multiple sources. Available with solder or press-fit pins, the device is also offered with an optional phase-change material.
