In this type of voltage stabilizers, voltage regulation is accomplished by switching the relays so as to connect one of a number of tappings of the transformer to the load (as in the manner discussed above) whether it is for boosting or bucking operation. The figure below illustrates the internal circuitry of relay type stabilizer.
This means that the flying capacitor voltage should be stable at any operational conditions. For that purpose, the inverter theoretically requires the symmetric switching of control signals with a phase shifting.
In this study, voltage balancing of the flying capacitor as well as the DC link capacitors under soft-switching operations is characterized through both simulation and experimentation. A voltage balance of a flying capacitor means that the two inner devices can then be clamped like that of the conventional two-level inverter.
Voltage balancing in the flying capacitor multilevel inverter (FCMI) is very important in maintaining the voltage balancing between the flying capacitors for a safe operation. This means that the flying capacitor voltage should be stable at any operational conditions.
As the name suggests, static voltage stabilizer doesn’t have any moving parts as a servo motor mechanism in case of servo stabilizers. It uses power electronic converter circuit to achieve voltage regulation rather than a variance in case of conventional stabilizers.
The output voltage from the stabilizer will stay in the range of 220V or 230V in case of single phase supply and 380V or 400V in case of three phase supply, within given fluctuating range of input voltage. This regulation is carried by buck and boost operations performed by internal circuitry.
