1 G9000 Series UPS Presented By: Erik! K. Monisera! Product Manager, G9000 UPS!

2 G9000 UPS 225 kva G kva G9000

3 G9000 UPS Topology 480V input / 480V 60Hz, 3-phase 3-wire output! Transformerless Design (lower weight, less heat discharge)!

4 You May Hear:! No transformer means no galvanic isolation.!

5 Designed For Data Centers Typical Data center has lots of galvanic isolation, on input and at load! No neutral needed on output when feeding a transformer!

6 You May Hear:! What is the kaic rating of the UPS?!

7 kaic: kiloamps Interrupt RaCng No breakers in G9000 Add fuses in bypass path to give unit a kaic rating

8 Full IGBT RecCfier

9 What IS Generator CompaCbility? Rectifiers are switching power supplies Notches and spikes in reflected waveform, wreak havoc on controls Harmonic currents cause heating in generators Solution: Oversize Generators

10 6- Pulse SCR RecCfiers 6-Pulse Rectifier: THD ~ 30% 5 th, 7 th, and 11 th harmonics dominant 2.5x Generator oversizing typical

11 12- Pulse SCR RecCfiers 12-Pulse Rectifier: THD ~ 10% 11 th and 13 th harmonics dominant 1.5x Generator oversizing typical Transformer needed

12 Full IGBT RecCfier / Converter IGBT s are fired in such a manner that allows the DC bus to be stepped up and controlled Voltage regulation +/- 1% Wide voltage input window +15 / -20%

13 Full IGBT RecCfier / Converter PWM with IGBT s reduces low-order harmonics High freq noise mitigated by small Low-pass filter Input current THD < 3%

14 Full IGBT RecCfier / Converter Reflected From UPS From Utility Phase of Converter voltage is displaced by firing of IGBT s Reflected Power Factor Corrected (>.99) Generator Friendly: 1.1 to 1 (Gen kw to UPS kva)

15 You May Hear:! Do you have a contactor that disconnects the input filter when the UPS goes to Generator operation?!

16 CompeCtors need this, we don t Input cabinets with 12-pulse rectifier and input filters can add 2 to width, hundreds of pounds, and 20% more heat discharge! input filters on competitors UPSs need to be huge to handle high degree of low order harmonics Enough capacitance to make UPS seem like leading PF load to generator

17 DC to DC Charger/Chopper

18 DC to DC Charger/Chopper: Charge Mode Q1 fired at 12kHz, Charging current supplied to batteries DCL 1 smooths out AC ripple from rectifier Charge current controlled by firing of Q1 Isolates batts from DC bus, limiting ripple current Regulates charge rate, helps prevent thermal runaway

19 DC to DC Charger/Chopper: Discharge Mode Q4 fired at 4kHz - Building/Collapsing of field of DCL1 now more pronounced Controlled firing of Q4 through DCL1 causes voltage boost Boosts battery voltage applied to DC bus Maximizes efficiency of the battery string

20 Hybrid StaCc Transfer Switch

21 Hybrid StaCc Transfer Switch Hybrid = Mechanical and Semiconductor technology Bypass} Static Transfer Switch SCR Switch SCR switch overlaps transfers to bypass 83MC2 SCR-fired transfer ensures no breaks; contactor takes stress off SCR s Inverter} 83MC1

22 Hybrid StaCc Transfer Switch: Advantages Heat is the enemy of semiconductors Contactor removes load from Thyristors, relieving them of heat MTBF with Bypass: > 3,000,000 hrs.

23 You May Hear:! Is the Static Switch fully rated?!

24 Fully Rated SS Assembly Static switch and SS contactor work in unison; SS assembly is fully rated Withstand rating of a contactor far higher than an SCR Design advantages: Highest MTBF in industry Distributed Bypass

25 G9000 UPS kva 225kVA G kVA G kVA G9000

36 TTC Toshiba Tie Cabinet No Intelligence in Tie Cabinet All load sharing and system control internal to UPS modules Communication between UPS s via redundant CAT5 cables Parallel hardware is field installable

37 You May Hear:! You need to either balance the cable lengths or add reactors to match the impedances of the bypass paths.!

38 TTC Toshiba Tie Cabinet No Reactors necessary Impedance must be matched Rule of thumb: 10% max delta for cable length If not possible, reactors can be added to power path

42 Parallel System OperaCon (Distributed StaCc Bypass) Normal Operation: Green Maintenance Bypass: Blue On Static Bypass: Red UPS #1 UPS #2 UPS #3 UPS #4 Toshiba Tie Cabinet (TTC) Once the load exceeds the maximum capacity all modules go to static bypass with no interruption to the load

43 You May Hear:! If one contactor fails to close, you will lose the load, because the others wonʼt be able to handle the total load.!

44 Distributed Bypass: Advantages over System StaCc Bypass One line showing MMS with typical competitor s SCC bypass cabinet

45 Comparing Parallel Bypasses: Centralized System or Centralized Bypass: No Redundancy More space and weight More cost

46 Comparing Parallel Bypasses: Distributed Distributed Bypass: Redundant design Obvious choice for tight space Perfect for N+1 systems Even if one bypass fails to close, load still supported
