Asymmetrical output voltage of inverter is desired for electrochemical power supplies. How they are utilizing the asymmetrical output voltage? Can anyone explain?
Dear Punit,
Electrochemical devices are activated by unipolar power supplies. That is a DC power supply. If you have alternating voltage source which is a bipolar, one has to rectify the AC voltage to convert it to DC voltage. You also add filters after rectification to smooth out the ripples associated with the DC output. You van also regulate it using the proper regulators to render it as a constant voltage power supply.
All these topics are covered well in the literature of electronic circuits.
Best wishes
As load is varied, according to the voltage applied in electrochemical process, automatically the load current would be adjusted even with asymmetrical out put of all three phases, without neutral shifting.....
As Abdelhalim Zekry has noted unipolar or DC power supplies are used. The inverter is normally a high frequency single phase inverter which is able to produce variable DC using PWM and even used to provide special waveforms to improve electroplating quality as shown in the ref below.
