3 Phase 3 wire IGBT based Delta PWM type Voltage optimizer

MEDI has designed and developed three phase three-wire input, three-wire output (delta in delta out) Static voltage optimizer.
This is an IGBT based delta PWM topology - 100A to 500A each phase.
Advantages of delta PWM are: PWM is made between phase to phase instead of neutral to phase. Because of this neutral is not required for the working of unit. And the output has potential with existing neutral. The unit will work with three wire input and three wire output. Three phase load can directly be connected across three wire output. And single phase load can be connected from any one of the output to existing neutral.
Periodically the unit goes to fully uninterrupted bypass for a short while and measure actual power consumed by the load and come back to voltage optimize mode, measure the reduction in the power and calculate how much energy is saved. This is measured using class 0.5 certified 3 phase energy meter. These parameters are displayed in the LCD along with other parameters like voltage, current, power factor, harmonics etc
System has built-in datalogger. All the parameters are periodically saved to flash memory with date and time stamp. The device is also having a wireless Zigbee communication interface. A computer or other device can wirelessly monitor or download the data and thereafter upload to the Internet.

Nice! The output voltage seems to jump less than the sag seen in the input voltage. The waveforms are clean. I wonder how this behaves with uneven loads (say, a high power lamp in series with a rectifier diode to simulate loads like hair driers working in half heat mode).

[@hijazecell5471]

Did you try non linear loads as battary chargers and motor drives and smps and half wave loads?

[@kARTechnology]

381V to 433V input has very less range...
we have here nominal 440v, 470v (max) and sometimes upto 500v also, so it will simply go to bypass mode
price for 30kva?

[@annaoaulinovna]

Very successfull device its price is $10000

Mam I seen this video , I found volt veriation input/output , then we use without medi divice and direct connection load

How is working

[@banglapowerpack7052]

We 5kw 3 phase 3 wire IGBT voltage stabilizer, your have Bangladesh in distributer please send your. Good sell price

[@DanFrederiksen]

Is there a big enough problem with mains voltage in India to where this is necessary?

[@DriftHyena]

I couldn't answer that but I think it's to make sure the voltage is stable during transients or load surges

[@TheFastingIndian]

yes . lot of overleaded transformer s
