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?
No matter what 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 will have 100 times + the fault clearing current of the UPS module).
The Galaxy 4000’s inverter’s fast current limiting response protects it from damage while safely allowing the utility to safely clear the fault via the robust static bypass switch
no matter how much overload
Other UPS may suffer fatally from output shorts as the inverter may self destruct if it can not current and transfer to bypass safely
Galaxy 3000 with 150% rated fast current limiting inverter and fully rated transfer switch.
inverter fault
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.

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 with out damage
Fault Clearing Sequence Power Flow 1
UPS detects current on inverter exceeds 167% of nominal 2
Inverter shuts down (1/300 of a cycle) avoiding thermal overload 3
Static Transfer Switch opens simultaneously 4
Utility clears fault via fully rated Static Transfer Switch 5
UPS returns to inverter power when fault clears
Load protected throughout sequence

14. DPQ [Digital Power Quality] The heart of MGEs 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)
12/1/2018

15. DPQ Advantages Load Surge Management
Step loads or load surges common in just about all applications
i.e. starting distribution transformers, starting banks of servers, starting motor loads (chillers), medical imaging equipment
UPSs not capable of sustaining stable voltage during step loads can compromise the load by decaying the voltage under quick load changes
Most manufacturers quote <5% on specifications but some may not be true.
Devices with high start-up surges
IT equipment (switch mode power supplies)
Medical imaging equipment
Distribution transformers
Motor loads
Fluorescent Lighting
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.
12/1/2018

16. DPQ Advantages Active Harmonic Cancellation
Harmonics are reflected by most loads (especially IT loads) and pollute the critical bus
MGEs inverter technology recognizes the harmonics and produces correction pulses at a high enough resolution to cancel harmonics
The result is that the critical bus THD is limited to 3.5% avoiding problems associated with high THD
UPS Output
reflected harmonics
12/1/2018

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 (as low as 1:1 ratio) due to negligible reactive current
Reduction in component count
Increased reliability due to less components due to elimination of input filter
Wide frequency and voltage input range (<25%)
Generator voltage often drops when first loaded; the wide input range means the UPS won’t transfer to battery
No reliance on battery battery power sustain dynamic loads
The Galaxy UPS does not have to rely on battery power to maintain load changes prolonging battery life
MGE has over 15,000 IGBT rectifiers installed globally like the Galaxy 3000
12/1/2018

18. Clean Distortion Free Input Power IGBT Rectifier Advantages
Eliminates harmful distortion that is reflected back onto the utility from the UPS from disturbing sensitive equipment sharing the utility power
UPS w/ Input Filter
UPS w/o Input Filter
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.

19. IGBT Rectifier Advantages
Low input THD (<3%) at all load levels
SCR based rectifiers will show increased THDI as the load level increases.
This is because they are tuned only for nominal load (not dynamic)
IGBT rectifiers maintain the low THDI level uniformly throughout all load levels
This means that potentially harmfully harmonic distortion will not be reflected onto the utility and disturb equipment sharing the utility power
MGE has over 15,000 IGBT rectifiers installed globally
12/1/2018

20. IGBT Rectifier Advantages
Reduced generator sizing (as low as 1:1 ratio
A unity power factor on the input (PFC or power factor corrected input) means that there is no leading power factor or reactive current reflected onto the utility
Not having to oversize the generator for high reactive current allows for generator to UPS ratios as low as 1:1 saving up to a half the cost of the UPS module
MGE has over 15,000 IGBT rectifiers installed globally
12/1/2018

21. IGBT Rectifier Advantages
Reduced installation costs
IGBT rectifiers result in a reduced installation costs
This is because the input if power factor corrected lowering the current demand by up to 25%
Lower input current means smaller upstream breakers, transformers and cables and LOWER COST
MGE has over 15,000 IGBT rectifiers installed globally
12/1/2018

22. IGBT Rectifier Advantages
Increased Reliability
The Galaxy UPS does not require an input filter as the IGBT rectifier does not reflect harmonics (<3% THD w/o a filter)
This means less parts and fewer parts translate out to more reliability
MGE has over 15,000 IGBT rectifiers installed globally
