Static Voltage Stabilizer

[sahu]

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 distortion)

Pwm static avr

Please we need in wry this type of stabilizer for Cnc machine s pls

First of all, you are replying to a 2,5 year old thread..
Anyway, Sahu, could you share the schematic or some other details of the topology you mention?

I'm a new member. can any one suggest circuit ideas of PWM based Static Voltage Stabilizer

 

[alec_t]

Many (most?) conventional SMPS use PWM to stabilise their output voltage. Try googling for 'smps schematic'.

i've required AC to AC IGBT based Static voltage Stabilizer.can u suggest schematics / power diagram for that

 

[alec_t]

Sorry, I can't. Keep googling

I posted a link in post 4 if any one is that lazy It shows hundreds circuits. Don't any one know how to use google image it's the fastest way to find circuits.

If they would look they would find all these
