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.

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
Fault Clearing Sequence
Power Flow
UPS detects current on inverter exceeds 167% of
1 nominal

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”

Load Surge Management
Devices with high start-up surges
● 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 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.
APC by Schneider Electric – Name – Date
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%

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
● Prolongs battery life

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
APC by Schneider Electric – Name – Date
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

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
