Hi-Rel system is
designed with IGBT as a power device of inverter
& microcontroller based control. |
|
Easy control, excellent
switching characteristics & high reliability,
today makes IGBTs the best choice for medium &
high power UPS. They significantly improve UPS performance,
particularly in terms of efficiency, acoustic noise,
size & weight. |
|
Rectifier,
inverter & static switch are main components
of industrial UPS modules. |
|
Advantages of IGBT
based Inverter, Microprocessor / DSP based control |
| |
 |
Extremely Reliable
System due to latest devices used having lesser
mechanism of failure. |
| |
|
No parametric drift due to
digital technology. |
| |
|
Field programmable parameters
due to extensive use of software. |
| |
|
Excellent Transient Response
due to High switching frequency of MOSFET / IGBT. |
| |
|
Extremely low THD due to high
switching frequency. |
| |
|
Very High Efficiency due to
extremely low losses. |
| |
|
Fully compatible to handle
100% non-linear load due to fast correction circuit
& instantaneous monitoring of Output waveform. |
| |
|
Capable of adopting PWM &
DSP technology with high switching frequency. |
| |
|
Extremely low switching losses
so very high Efficiency. |
| |
|
Available up to 600 Amp. |
| |
|
Accepts a current twice its
related value without any significant variation
in its
voltage capacity. |
