1 Datasheet (Preliminary) Modular Inverter System VARIS Individual circuit arrangement or forced air cooled 60µF capacitance per module Optical or electrical signal transmission Current and temperature measurement 1. Technical Data Phase Leg 2. Technical Data -Phase Inverter General information: VARIS consists of a half bridge IGBT module with dc-link capacitors. One VARIS can be used as a phase-leg for AC inverters as well as a boost- or buck converter for DC operation. Three VARIS connected together result in a -phase inverter. For higher power, parallel configurations of the boost converter, buck converter or -phase inverter are possible. VARIS is available with water or forced air cooling, and an optical or electrical signal transmission. Each module has its own heatsink, driverboard and current sensor. For the technical data of the -phase inverter please see section 2. page 7. Version PRELIMINARY - Prepared: D.R. / Approved T.S. Page 1 of 1
