Constant Voltage Transformer

Operation of CVT

The allotment of the attractive center over which the optional slowing down wound is immersed while the parcel over which the essential wound is not soaked. A capacitor is joined over the optional slowing down block out the yield at a frequency near 50 Hz. This capacitor likewise makes the present in the optional slowing down increment which helps in the immersion of the auxiliary flux. Since the auxiliary air conditioning flux is limited to a soaked quality for an expansive reach of the info voltage (170-270 V), a steady voltage is accessible over the optional slowing down. The yield voltage won't be of an immaculate sinusoidal waveform yet will be an estimated sine wave with the crests flattened approaching a square wave. Yield voltage waveform of a CVT is demonstrated in figure. In figure, a repaying slowing down demonstrated associated in arrangement to the auxiliary to enhance the CVT execution.

Once the constant voltage transformer is put at the yield of a square wave inverter (in the UPS), mind must be taken to control the recurrence of the inverter, since the CVT is delicate to the recurrence of it’s include supply.

The reason we utilize a constant voltage transformer - CVT and not a voltage stabilizer for PC requisitions is that in the voltage stabilizer transfers are available and when these transfers work (switch), the yield voltage may be hindered for a brief time. Such a transient may not be attractive for workstations which may cause the workstation to reboot. The constant voltage transformer gives a clean without spike yield voltage. The voltage regulation conceivable in a CVT likewise is great.

The data voltage goes 170 to 260 V and yield regulation is 230 ± 2 % at no heap to full-stack. Distortion approx 5 percent under full load conditions. Rating of 50, 150, 250, 350, 500, 750, 1000, 2000 VA.
