5 KVA to 10 KVA Automatic Voltage Stabilizer Circuit – 220 Volts, 120 Volts

Last Updated on September 17, 2017 by Swag 74 Comments

The diagram shows a rather simple voltage stabilizer design which can hold huge output power in the order of 5 to 10KVA. The use of SSR or solid state relays makes the output stage easy to configure and very accurate - thanks to the modern SSRs which are designed to trigger massive power in response to smaller input DC potentials.

Circuit Description
The proposed circuit of a simple 5 KVA to 10 KVA automatic voltage stabilizer circuit is easy to understand. All the opamps are arranged in standard voltage comparator modes.

The presets P1 to P7 can be adjusted as per the required tripping points, which will correspond to the output SSR switching and the subsequent transformer tap selections.

The central green TAP is the normal voltage output, the lower TAPs gradually produce higher voltages while the upper TAPs are set for lower voltages.

These TAPs are chosen by the appropriate SSRs in response to the varying AC voltages, thus adjusting the output voltage to the appliances close to normal levels.

This circuit was asked by Mr. Alexandar and the SSR data was provided by him.

Parts List
R1 to R9 = 1K, 1/4 watt,

P1 to P7 = 10K preset,

C1 = 1000uF/25V

VR1 = 1K Preset,

opamps = IC 324,

Transformer = Input 230volts or 120volts, Taps - incrementing/decrementing voltage levels (TAPs) as per individual specs.

SSR = 10KVA/230volts = output, 5 to 32 volts DC = input
