Static Voltage Stabilizer is an IGBT based PWM type buck-boost voltage
stabilizer which has tight regulation and fast correction speed which is impossible to
obtain using conventional methods such as servo voltage stabilizers, SCR / triac type
stabilizer, relay type stabilizer etc.
This is an SMPS type voltage stabilizer for mains voltage (AC input and AC output).
This is a new switching topology where PWM is made directly in AC-to-AC
switching, without any harmonic distortion. In this topology there is no need to convert
the AC input to DC and again convert it back to regulated AC output. This simplifies the
design, reduces the component count and improves the efficiency and reliability. The
power stage is an IGBT chopper control. The chopping frequency is around 20KHz
which ensures absolutely silent operation and pure sine wave output (no waveform
