AC Source & Load

Programmable four-quadrant AC source & load

four-quadrant AC solution

This programmable AC source & load solution based on the COMPISO System Unit covers a wide range of use cases, from programmable four-quadrant voltage and current sources or sinks to PLL-locked current sources and on to passive impedance emulation. Standardized high-bandwidth test solutions provided together with ad-hoc programmable scenarios are scalable up to 1.2MVA.

programmable, flexible & versatile


4Q operating area with adjustable voltage, current and power limits


preset standardized tests and API for custom waveform sequence generation


PLL mode for grid synchronization applications with wide frequency variations


variety of waveforms, harmonics, sub- and inter-harmonics to cover even most demanding scenarios
