Power supply integrates harmonic neutraliser

This fifth-generation product now includes 65 models spread across independent 100kW, 150kW, and 250kW modules, with voltages from 16 to 4,000VDC and currents from 24 to 24,000ADC.

The MT Series V features Magna-Power Electronics’ signature current-fed power processing, delivering additional power processing stages for increased system protection under abusive loads.

The newest 250kW module integrates Magna-Power Electronics’ harmonic neutraliser, which suppresses families of AC harmonics by increasing the number of power phases.

The harmonic neutraliser creates a 12-pulse AC waveform, minimising harmonic distortion.

The harmonic neutraliser eliminates families of harmonic components by multiplying the number of input phases with specially wound autotransformers, providing a cost effective solution to maintaining power quality at acceptable levels.

By designing a 250kW module and integrating the harmonic neutraliser, the overall 250kW system size was reduced by more than 33 per cent.

In addition, the integrated harmonic neutraliser greatly reduces installation requirements, easing multi-module scalability.

The new MT Series V features identical controls and features as Magna-Power Electronics line of programmable DC power supplies.

All the products come standard with RS-232 interface, programmable SCPI command set, isolated 37-pin I/O for PLC integration, and rotary front-panel control, metering and calibration.

Also available are programming options, such as LXI TCP/IP Ethernet (+LXI) and IEEE 488.2 GPIB (+GPIB), as well as performance options, such as photovoltaic power profile emulation (+PPPE) and the recently released high slew rate output (+HS).

Units are capable of master/slave parallel and series operation through the plug-and-play UID46 device.
