1.2.1 DESCRIPTION OF BLOCKS  
 

 

RECTIFIER:

 In DS300 HYB Series UPSs, a DSP controlled IGBT rectifier with PWM technique is used to 

increase input power factor (PFC) and to decrease input current harmonics (THDI).  
The  IGBT  rectifier  accepts  3-phase  AC  input  and  produces  a  dual  polarity  DC  voltage  for  both  supplying 
the inverter and charging the batteries.  

 
BATTERIES: 

Batteries are used as reserve DC power supply for the Inverter in case of mains failure. In 

DS300 HYB Series, batteries are connected in series with a center-tap output to obtain a dual polarity DC 
supply. 
Batteries are discharged by  the  inverter during mains failure. The discharged batteries are re-charged by 
the IGBT Rectifier on a constant voltage / current limiting basis, if AC mains power is available. 
 

INVERTER

: It is manufactured by using the latest IGBT and DSP (Digital Signal Processing) technologies, 

and Pulse Width Modulation (PWM) technique. The Inverter converts the DC BUS voltage supplied by the 
IGBT Rectifier and / or the batteries into  a  well regulated, fully digital controlled 3-phase  AC  voltage  with 
fixed voltage and frequency. 
The output of the inverter is used to supply the critical loads connected to the UPS output. 

 
STATIC  TRANSFER  SWITCH  (STATIC  BYPASS): 

This  is  an  electronically  controlled  transfer  switch, 

which enables the critical load to be connected either to inverter output or to by-pass power source. During 
normal operation, the load is supplied by the inverter output, but in case of an overload or a UPS failure it is 
automatically transferred to the bypass source without any interruption. 
 

MAINTENANCE BYPASS SWITCH (MBS): 

This is a manually controlled mechanical switch, which is used 

to  supply  the  critical  load,  using  the  bypass  source,  when  the  UPS  is  shut  down  for  maintenance  or 
troubleshooting purposes. 
The load is unprotected against mains supply disturbances and black-outs when it is connected to either 
static or maintenance bypass supply.  
 
 

1.2.2.  OPERATING CONDITIONS OF UPS 

 
    UPS may be in one of the following operating conditions: 

 

A.  Normal Operation (If Mains supply is available): 

All fuses and power switches are closed (except the Maintenance Bypass Switch), and the load is supplied 
by  the  Inverter  Output.  During  normal  operation,  the  Rectifier  supplies  DC  power  to  the  Inverter  and 
charges the Batteries at the same time. 

 

B.  Battery Operation : 

The Batteries are connected to the Rectifier output. In case of a mains failure (mains power outage or AC 
input voltage out of tolerance), the Rectifier stops operating and the DC voltage necessary for the inverter 
operation  is  supplied  by  the  batteries.  Therefore  the  AC  voltage  output  supplying  the  critical  load  is  not 
interrupted, until the batteries are fully discharged. At the end of the discharging time the inverter is turned 
off and it start again  automatically, together  with the rectifier,  when the mains  power  is restored,  and the 
UPS returns o normal operation. For UPS with a split bypass source, at the end of discharging time, static 
transfer switch transfers the load to the split bypass source without interruption if the split bypass source is 
available  and  in  acceptable  tolerances  about  voltage  and  frequency,  as  still  the  rectifier  input  is  not 
available.  
The Rectifier is also turned off and inverter operates on batteries during automatic or manual battery test 
procedure.  
 

C.  By-Pass Operation : 

If the Inverter output is overloaded or in case of a problem in the UPS, the static switch transfers the load to 
the  bypass  supply  without  any  interruption,  provided  that  the  bypass  supply  is  available  and  within  the 
tolerated limits regarding voltage and frequency. At the end of the overloading period, if the fault condition 
is restored, static switch transfers the critical load again to the inverter output. Note that, during operation 
from the bypass supply, the critical load may be effected by any possible disturbances or power failure in 
the bypass supply.
