"Saving Power Through Energy Efficiency is a World Priority"

Most digital electronic devices are susceptible to radio frequency interference.  This interference can be conducted by air or hard wire.  It is such a significant problem in electronic equipment, that a large global market has developed to cope with this problem.  Electromagnetic interference or radio frequency interference is any disturbance or degradation in a product caused by an outside signal.

It is estimated that the global market for RFI materials and technology is 4.5 billion in 2011 and increase to 5.2 billion by 2016. [Electronics Industry Market Research]

A major contributors to this problem is the switching of current loads. If current loads are not switched properly, the stored energy of the current pulse can generate a substantial noise pulse.


One of the major attributes of the voltage regulator developed at VSquare/R is the unique way it switches its cycles.  All switching is conducted when the energy in the load is at or near zero.  Thus, the noise level generated at switching is substantially reduced.



Electrical Energy Usage

Minimum line voltage operation:

When engineers design a product, it must be designed to safely operate between minimum  and maximum line voltage. As a result, when the units operate at nominal line voltage, they can consume excess energy which can be wasted.

It is highly desirable that products control their voltage at minimum line voltage regardless of the supplied source voltage. 



Load variations:

Load variation is another factor that wastes energy. A classic example is the washing machine. The motor is sized to provide the energy for large loads.  As a result, the energy used by the motors for minimal loads is  excess energy which is wasted.

Therefore, to conserve energy, it is highly desirable that the voltage delivered to the motors only supply the energy necessary to operate the load. Any excess energy could be wasted energy.


Voltage variations:

The voltage supplied is often set at a fixed Voltage with a nominal rating. The voltage should be set to obtain the desired performance at the lowest voltage.  As the load or performance changes the voltage should be adjusted accordingly.

The line voltage can vary from minimum to maximum.  As a result, if a product can properly operate at 105 volts and the power source varies up to 130 volts, it can consume the excess energy, which can be wasted energy if not utilized.
