A Test Arbitrary Waveform Generator

The results from the development of a three-channel arbitrary waveform generator with the function of a programmable power supply for setting up and debugging automatic control system boards for converter devices that require synchronization with the network are presented. The features of the device are the ability to simulate a three-phase distorted network to check and adjust the synchronization of control boards and the presence of galvanic isolation between three channels, which allows for using the generator as a power source for three-phase circuits. The generator provides the formation of output signals for each of the channels in the voltage range ±25 V with a maximum current of up to 2 A. The frequency range of alternating signals of the generator is 0.01–10 kHz. Currently, the generator is used at PAO Elektrovypryamitel to simulate dips, network distortions, and phase imbalances and to tune phase-locked loop systems and analog and digital filters.
