Precision Power Labs performed an extensive evaluation on energy saving
devices prior to the introduction of a new line called the IntegraPower Home
and Industrial motor controllers. The first type of device simply added
capacitance and did not truly save energy as measured by the AC Power
utility provider. The second type operated by switching the power on & off
very quickly, reducing the average effective voltage. Not only did this type
reduce the speed of the motor but it also got hot from the power it consumed
by switching on & off the AC power. The combined effect could be that
more energy was being used while the motor was running slower.
The engineers at PPL started with the NASA patent for saving energy on AC
motors, and applied the latest Digital Signal Processor (DSP) technology to
actually improve the power factor while reducing the energy consumption.
This picture from Advanced Energy shows the voltage leading the current in
an AC Motor with a poor power factor.
When you look at the AC sign wave you can see how the voltage is positive
for ½ of the cycle and negative for the other half. When it is at 0 volts you
could consider it as being off for that split second. Without divulging our
zero voltage switching technology we can offer the following explanation:
If the application of the AC Voltage is delayed for a given period of
time on every half cycle of the AC sine wave, the power consumption
area (shown in yellow above) can be met in less time. If this time
period still includes the peak voltage of the AC sine wave then the
motor speed is maintained. The power factor can be improved for the
AC motor and the utility provider will deliver less energy resulting in
a reduced energy bill.
While NASA was able to figure a way to accomplish this for a single phase
AC motor nearly 30 years ago, it has been very difficult to accomplish on 3
phase AC motors. As technology improves and higher computing power is
available at lower cost things are being done now that was not possible a few
years ago. Steady loads are easier to control however real life industrial
loads are seldom steady. Loads fluctuate as well as the AC voltage and the
internal construction of the motor windings. All of this makes for a difficult
control scenario. The IntegraPower controller meets these requirements.
