The diagram demonstrates an extremely very simple voltage stabilizer design which are able to maintain massive output power approximately 5 to 10KVA. The application of SSR or solid state relays tends to make the output stage convenient to configure and very precise - thanks to the latest SSRs which are usually built to activate enormous power as a reaction to smaller input DC potentials.
The suggested circuit of a basic 5 KVA to 10 KVA automatic voltage stabilizer circuit is simple to recognize. All the opamps are organized in regular voltage comparator modes.
The presets P1 to P7 can be modified as per the needed tripping points, which is able to correspond to the output SSR switching and the successive transformer tap alternatives.
The central green TAP is the regular voltage output, the lower TAPs steadily generate much higher voltages while the upper TAPs are set for lower voltages.
These types of TAPs are selected by the suitable SSRs as a reaction to the varying AC voltages, thus modifying the output voltage to the appliances near to regular levels.
