Magna Power DC Power MT SeriesHigh power cabinet style programmable DC power supply • expandable up to megawatts
Overview
Magna Electronics' MT series products use the same reliable current fed power processing technology and control method as other products in MagnaDC's programmable power supply product line, but have larger power models: 100kW, 150 kW, and 250 kW specifications, respectively. The MT series products based on high-frequency IGBT are one of the standard program-controlled DC power supply products with the highest single power on the market. Compared with low-power models, they minimize the number of switching components to the greatest extent possible. The UID47 device can achieve megawatt power level expansion, providing master-slave control: one master control power product controls other slave power products to achieve true system level operational control. All MT series products are equipped with rated full power AC input circuit breakers as an additional safety protection measure. The 250 kW model comes standard with an embedded 12 pulse harmonic neutralizer to ensure lower THD (total harmonic distortion). Higher quality AC waveforms can be obtained through an external 500 kW 24 pulse or 1000 kW 48 pulse harmonic neutralizer, which is specifically designed and manufactured by Magna Electronics for its MT series products.

Magna Electronics' harmonic neutralizer eliminates harmonic component families by multiplying the input phase number with a special wound magnetic component, thereby reducing total harmonic distortion (THD). These magnetic components can be combined with high-power DC power supplies of the same load, providing a low-cost solution to maintain power quality at an acceptable level, allowing customers to benefit from reliable high-frequency switching power supplies from Magna Electronics and expand to the megawatt level. The 12 pulse harmonic neutralizer is embedded in all 250 kW models, and its installation is very simple for end users. For applications that require THD levels better than 12 pulse waveforms, Magna power supplies provide external 24 pulse and 48 pulse harmonic neutralizers.
Why neutralize harmonics?
Input current harmonics are a byproduct of almost all power sources. Electricity can only be delivered to the load when the frequency and phase of voltage and current match. For a three-phase power supply using a three input rectifier, the theoretical frequency spectrum of the input current is 6n ± 1. Among them, n is an integer increasing from 1; This is the so-called 6-pulse waveform. This means that a power supply equipped with three input rectifiers will generate input current at 1/3/5/7/9/11/13/15/17/19 times the fundamental frequency. The theoretical amplitude attenuation is the reciprocal of the harmonic component. The amplitudes of the 5th and 7th harmonic components are 20% and 14% of the fundamental frequency, respectively. Harmonic currents in power systems may have abnormal paths, and if the amplitude is large and there are loads sensitive to harmonic frequencies, it may cause problems. For example, lighting ballasts have capacitors and inductors connected in series, which can be excited by harmonic currents. IEEE has introduced the standard IEEE 519, which specifies recommended limitations. Implementing this standard requires an understanding of the power system and other loads that generate harmonics. Unfortunately, this standard may allow the same power source to exceed limits in one application, but not in another. In the same aspect, the power supply may or may not cause harmonic related issues with or without compliance with IEEE 519.

Current fed topology control structure: powerful power conversion capability
safety design
MagnaDC programmable DC power supply has a wide range of diagnostic functions, including:
• Lack of communication
• Overheating conditions
Overvoltage trip (programmable)
• Overcurrent trip (programmable)
• Clear the fuse
The programming line voltage is too high
When in standby mode or diagnosing faults, the AC power supply is mechanically disconnected through an embedded AC contactor to ensure that the device only operates on power when needed. Finally, through a dedicated+5V interlock input connector and all models containing+5V reference values, the external emergency braking system can be easily integrated using an external contactor
The included software interface: RIS panel remote interface software is standard for all power supply models. This software provides users with a simple and intuitive method to operate Magna power supplies through remote computer control. The remote interface software has six windows: virtual control panel, command panel, and registration panel.
The master-slave operation strategy of the high-performance plug and play MagnaDC programmable DC power supply ensures that adding devices in parallel or series does not reduce performance by directly providing gate drive signals from the primary device to the secondary device. In addition to maintaining a single control loop, this approach can also eliminate common noise susceptibility when sending analog control signals over long distances. UID47 simplifies the master-slave parallel or series configuration of Magna Electronics' DC power supply and achieves nearly equal current or voltage distribution based on this configuration.
Wide programming support: All MagnaDC programmable DC power supplies are equipped with dedicated LabVIEW from National Instruments in the United States ™ Drivers, interchangeable virtual instrument (IVI) drivers, and support for various programmable instrument standard commands (SCPI). These programming interfaces support full control, measurement, and monitoring of MagnaDC power supplies. All MagnaDC power supplies have usable communication interfaces and are compatible with the following drivers and command sets: RS232, LXI TCP/IP Ethernet, IEEE-488 GPIB, USB, or RS485.
External isolated I/O interface for hardware in the loop or PLC control
By using the isolated 37 interface I/O connector on the back panel of the device, complete control and monitoring of the MagnaDC programmable power supply can be achieved through external signals. By applying a 0-10V analog signal, the set points for voltage, current, overvoltage, and overcurrent can be set. Each diagnostic condition is equipped with a designated interface, which reads+5V when it is too high. By providing reference signals (+5V and+10V), the need for external voltage signals can be eliminated and dry contacts can be allowed to be used. In addition, the power supply has a normally closed external interlock, which allows the power supply to be associated with other emergency stop devices when activated. All these interfaces are isolated from the output end and based on ground - no additional isolation devices or options are required.
The following summarizes the available I/O of the power supply:
• 4 Analog inputs
• 2 Analog outputs
5 digit inputs
15 digital outputs
After equipping the+2.5V,+5V, and+10V reference signals with the high conversion rate output (+HS) option, high bandwidth operation can be enabled with rapid rise time, enabling MagnaDC programmable DC power supply to meet hardware in the loop (HIL) requirements
