INTRODUCTION :

HPI-D series Inductive Voltage Regulator / Magnetic Induction Automatic Voltage Stabilizer (Brushless / No Sliding Contacts Design) is available from 100 to 5,000KVA as standard, in Single or Three-phase Output configurations.
The HPI-D series Inductive Voltage Regulator pay for themselves.
No matter what the application, variations in voltage can cause considerable loss of time and money.
By reducing unnecessary downtime and costs, the HPI-D series IVR can actually pay for themselves.
What’s more, alternative methods for solving poor voltage problems are usually more expensive than IVRs. Contact your local Satech Power Sales Engineer. He or she will welcome the opportunity to review your problem and help you solve it.

PRINCIPLE :

Inductive Voltage Regulator mainly composes of two structures:

1. Mainframe: Inductive Voltage Regulator, initial as IVR.

The Industrial grade Inductive Voltage Regulator is a variable ratio Auto Transformer consisting laminated steel Rotor (called as “R”, the shunt winding) and Stator (called as “S”, series winding).

Functions by the electromagnetic reaction of shaft core with Rotor, to result in relative rotation of both counterparts, thus achieving alteration in the phase of the induced electromotive potential, as seen in a stabilized output.

Transmission is controlled by electric power, whereby Driving Motor is used to drive gear, and alter output voltage which is to be registered in IC chips, once a voltage fluctuation occurs -- going up or down, a command will release to the Driving Motor for adjustment of its phase angle, and that to result in a corresponding change in Output voltage, so that free going voltage regulation is attained without any shifts.

The winding inside Rotor is called Primary Winding (Input), which connects in parallel with input power wire; the Stator is a Secondary Winding (Output) which connects with the same load in series. Secondary Voltage varies with intersecting angle “θ” of both winding. (shown as below figure).

E1 (between 3 and 4) = Input Voltage (Primary Voltage)
(The voltage inducted by the Secondary winding shall vary to the angle between the two coils)
- E2 = E1 cos.θ, vary continuously
- Output Voltage = E1+E2 = E1 (1+ cos.θ)
- When R & S is in parallel, E2 is Increasing (clockwise),
Output Voltage = E1+ (+E2)
Output Voltage = E1 + 0 = E1
- When R & S is in –90deg., E2 is Reducing
(anti clockwise), Output Voltage = E1 + (-E2)

Because of opposite position between Primary and Secondary Winding, output voltage can be adjusted continuously depends on alternation of primary Flux Density even connected with load.

2. Voltage Regulation Structure:

By use of Logic circuits to detect output voltage variation.
When output voltage rate is within +/-1% setting value (1% ~ 3% Adjustable), it will command No Contact Point Relay (SSR) to conduit for no contact point, step-less automatic regulation.

Industrial grade Inductive Voltage Regulator has advantages of

a) No Output Distortion;

b) Pure Sine Wave Output;

c) No Sliding Contacts or Brushes inside;

d) Strong Overload Capability.

It is the only type to be able to fabricate thousands KVA, Powerful Overload Capacity with Minimum Failure Rate.
