12. Fault Tolerant Circuitry Manages faults without compromising the UPS
Output faults are relatively common over the life of any electrical system – will your UPS be able to handle them?
Regardless of the overload capacity of the inverter (i.e. 150% or 300%), it’s not enough to handle output faults which range from around 600% to infinite current.
Only the utility has enough power to clear most output faults safely (usually 100 times + the fault clearing current of the UPS module).
The inverter’s fast current limiting response protects it from damage while allowing the utility to safely clear the fault via the robust static bypass switch
regardless of the overload
Other UPS may suffer fatally from output shorts as the inverter may self destruct if it cannot current limit and safely transfer to bypass.
Galaxy 3000 with 150% rated fast current limiting inverter and fully rated transfer switch.

Brand A
Output faults are common events on any UPS system. Even a small downstream device fault may take four or five cycles before a distribution circuit breaker opens. This means that the UPS module must be capable of clearing the fault.
The reality is that no UPS manufacturers inverter has the capacity to clear very large faults. IGBTs (the transistors) used in the inverters simply are not designed to sustain faults.
The key to managing faults is to firstly protect the inverter by current limiting it from fault conditions – and then safely make a seamless transfer to utility via the static bypass switch. The utility will have enough fault clearing capacity to clear any fault.
Since the inverter is properly protected once the fault is cleared (either by opening the breaker or if it clears itself) – it can safely assume the critical again.
MGEs fast current limiting avoids overloading the inverter – while the robust static bypass switch feeds enough utility power to clear the fault. The result is that the load will stay protected and the UPS will remain in tact.
Brand A with 300% rated inverter and slower transfer switch.
Presentation Title

13. Fault Tolerant Circuitry How fault tolerant circuitry works
Fault tolerant circuitry relies on two critical features
Inverter is fast enough to current limit (switch off) and avoid being overloaded by excessive fault currents
Static transfer switch can sustain enough current to clear the fault without damage
Load protected throughout sequence
UPS returns to inverter power 5
Utility clears fault via fully rated Static Transfer Switch 4
Static Transfer Switch opens simultaneously 3
Inverter shuts down (1/300 of a cycle) avoiding thermal overload 2
UPS detects current on inverter exceeds 167% of nominal 1

14. DPQ [Digital Power Quality] The heart of MGE’s performance advantage
Output created from hundreds of variable width pulses (Pulse Width Modulation)
Control Loop compares output to a references sine wave and makes adjustments or correction pulses to maintain a “power quality envelope”
Power Quality Envelope (<1% V)
Output Voltage
Up to 8 cycles per mS (132 / cycle)
Presentation Title

15. DPQ Advantages Load Surge Management
Devices with high start-up surges
IT equipment (switch mode power supplies)
Medical imaging equipment
Distribution transformers
Motor loads
Fluorescent Lighting
Step loads or load surges are common in most applications
i.e. starting distribution transformers, starting banks of servers, starting motor loads (chillers), medical imaging equipment
A UPS not capable of sustaining stable voltage during step loads can compromise the load by decaying the voltage under quick load changes
IT FACT: starting up one bank of servers can cause power surges equal to the rating of a 30 kVA UPS and may decay your UPS voltage.
Presentation Title

16. DPQ Advantages Active Harmonic Cancellation
Harmonics are reflected by most loads (especially IT loads) and pollute the critical bus
MGE’s inverter technology recognizes the harmonics and produces correction pulses at a high enough resolution to cancel harmonics
The result: The critical bus THD is limited to 3.5%
UPS Output
reflected harmonics
Presentation Title

17. IGBT Rectifier Advantages
Constant and low input THD (<3%) attenuation at all load levels
Will not disturb sensitive loads sharing the utility / input
Reduction of RMS current
Reduced installation costs (sizing) / current consumption reduced by up to 25%, allowing smaller upstream breakers, transformers, and cables
Unity (0.99) input power factor
Reduced generator sizing due to negligible reactive current
Reduction in component count
Increased reliability
Wide frequency and voltage input range (<25%)
The UPS will not transfer to battery if the generator voltage drops
Does not rely on battery power to sustain dynamic loads

(utility power)
Distortion reflected back from UPS input onto other devices sharing utility power
UPS w/o Input Filter
Galaxy 3000 w/ IGBT Rectifier
Input harmonics are harmonics (electrical pollution) that are reflected back from the UPS input to the utility. Devices that share the utility power in the facility will see these harmonics and can easily be disturbed by them.
By using a power factor corrected transistorized (IGBT) rectifier the Galaxy 3000 draws voltage and current at the same rate, and thus does reflects practically no harmonics on the utility making it perfect for computer environments where other sensitive devices share the utility power.
Other UPSs that do not have PFC input must use large input filters to limit harmonic distortion. These filters often have capacitors that will distort the power factor of the UPS as well as create reverse current that will cause problems when pairing the UPS with a generator.
The Galaxy 3000 reflects less than 3% THD (total harmonic distortion) onto the input – less than the best input filter on any UPSs.
Presentation Title

19. IGBT Rectifier Advantages
Low input THD (<3%) at all load levels
IGBT rectifier maintains a low THDI level uniformly throughout all load levels
Potentially harmful harmonic distortion is not reflected back onto the utility to disturb other equipment sharing the line
MGE has over 15,000 IGBT rectifiers installed globally
Presentation Title

20. IGBT Rectifier Advantages
Reduced generator sizing
A unity power factor on the input (PFC or power factor corrected input) means no leading power factor or reactive current reflected onto the utility
Eliminates generator oversizing (low generator to UPS ratio) - saving up to half the cost of the UPS module
Presentation Title

21. IGBT Rectifier Advantages
Reduced installation costs
The power factor corrected input lowers the current demand by up to 25%
Lower input current means smaller upstream breakers, transformers, and cables
Presentation Title

22. IGBT Rectifier Advantages
Increased Reliability
The IGBT rectifier eliminates the need for an input filter (<3% THD w/o a filter)
This means fewer parts - fewer parts means greater reliability
