Static
Stabilizer (New Design) |
| This is an SMPS type voltage stabilizer for
mains voltage (AC input and AC output). The power stage is an
IGBT chopper control. The chopping frequency is around 20KHz
which ensure absolutely silent operation and pure sinewave
output (no waveform distortion). |
| The
control section is based on dsPIC controller which ensure quick
correction of output which is not possible in conventional relay
type stabilizer or servo controlled stabilizers. The circuit is
having LCD display which will show all parameters like: input
voltage, output voltage, connected load, your company name (We
will program your company name in the dsPIC at the time of
technology transfer) etc. |
| The
transformer size will be only 1/4 th of the output power. For
2KVA stabilizer transformer size will be that of 500 VA. |
|
Since the
circuit is fully solid state (no mechanical or moving parts)
there will not be any ware and tare like the brush tare in servo
stabilizer or relay degrading in relay-based stabilizer. |
Features
1. Rapid cycle by cycle correction of output.
2. Outpt regulation of +/- 1% which is impossible in
conventional stabilizer.
3. No distortion in output waveform.
4. Overload cutoff
5. Overvoltage and under voltage cutoff.
6. LCD display for displaying all parameters and your company
name.
7. Small transformer size.
8. 20KHz PWM control
9. IGBT power stage. Highly reliable.
10. Fully solid state. No moving part, hence more life and no
maintainance.
11. Silent operation. |
