_2015_v1 CINERGIA s Programmable Power Supplies are power electronics equipment designed to generate a constant voltage, current or power. Thanks to its bidirectional hardware the can source or sink the test energy while the grid-tied converter will actively regenerate the energy back to the electrical grid consuming a sinusoidal current with unity power factor and low harmonic distortion. FUNCTIONAL DESCRIPTION Operation modes: -Constant Voltage (CV) -Constant Current (CC) -Constant Power (CP) -Automatic test from Excel file It provides three channels: -The three channels can be controlled independently, allowing different voltage, current or power setpoints -The three channels can be controlled in parallel, sharing the same setpoint and providing 3 times the current -In Unipolar 2Q applications, the loads will be connected between one channels and the common negative. -In Bipolar 4Q applications, the loads will be connected between two channels KEY FEATURES 6.75 160 kw 2/4 Quadrant Power Supply Regenerative up to % rated power 1 channel Output: 0 to 750V, 0 to ±690A 3 channels Output: 0 to 750V, 0 to ±230A/ch Bipolar Output -750 to +750V, 0 to ±230A CV, CC, CP modes CINERGIA Pere IV 29-35, 5è 1ª 08018 BARCELONA cinergia@cinergia.coop T. +34 934 864 358 Caltest Instruments GmbH Kohlmattstrasse 7 D-77876 KAPPELRODECK info@caltest.de Tel: +49(0)7842-99722-00 Fax: +49(0)7842-99722-29 www.caltest.de
_2015_v1 CONCEPTUAL SCHEMATIC Power Supply GRID AC EQUIPMENT UNDER TEST (EUT) BACK-TO-BACK TOPOLOGY Optional The converter is formed by a grid-side Active Rectifier and an output converter sharing a -link. The Active Rectifier allows sinusoidal current consumption with low harmonic distortion and unity power factor. The converter generates three independent voltages controlling the voltage, current or power.

Galvanic isolation is recommended. AC Output is connected to the Equipment Under Test (EUT) and can be used as: - Three independent 2Q channels - One 2Q channel (3 times rated current) - One 4Q bipolar channel (connecting the load between two channels)
