6.4  Operating  the  Inverter  Using  Single+- 
Power 
Sw 
li 
single-phase power supply  is  used 
to 
operate the  inverter  only 
2/3 
of  the diodes will  be  used, 
and ripple  current  of  the capacitor  will  increase  compared 
to 
operation with three-phase power 
supply,  resuiting  in  higher  temperature  rise  of  the  converter  and 
the 
capacitor. Operating the  in- 
verter  using a Single-phase power supply  requires  derating  the output current.

supply 
(1) 
Connect the single-phase power suppty 
to 
the  terminals 
R 
arid 
S 
of 
the inverter. 
(2) 
If 
capacity 
of 
the power supply is  insufficient,  the 
output 
voltage will 
become 
unstable under 
changing  load  conditions.  Therefore, 
be 
certain  the  power supply is adequate.
