Our UPS system utilizes the state of
art Space Vector theory with Pulse
Width Modulation technology which
reduces the switching losses by
limiting the switching to the two
third of the pulse duty cycle. As
the PWM signals have to be
calculated in real time, by using
Space Vector Modulation the
calculation process is simplified
and hence less computing time is
required which results in better
performance.
Configuration
The system configuration can be a
Double Conversion Online type with
isolation transformers at both Grid
and Load side. The load shall
normally fed by the Inverter through
the Static Switch. Provision can be
given for paralleling of the
systems.
Space Vector techniques gives full
use of DC voltage ceiling and lowers
the DC currents. This gives lower
cost of complete power stage and
magnetics. Control is approximately
10 times more accurate than
conventional PWM methodologies. Our
systems use a multilayer DSP control
with 12 bit analog sampling. This
products high accuracy and
subsequent smoothness of power
flows.
