LV Power technology is based on a new development in the field of power conversion we call it.
B.E.C.S. - Bidirectional Energy Conversion System
B.E.C.S. - Bidirectional Energy Conversion System.
The entire function of a power supply is to convert electrical energy from one form to another in the most efficient way possible.
In a complex system this is done several times.
1) AC Line to DC 48V
2) DC 48V to Internal Bus Architecture (IBA) 12V
3) IBA to point of load 5V, 3.3V ,1.1V, 0.8V
Even if each of these conversions were 90% efficient …. And they are not, the overall conversion efficiency will be 0.9 x 0.9 x 0.9 = 0.73% . Real life systems are between 0.65-0.70% efficient.
The B.E.C.S system is working on two principals.
A) The use of both zero voltage and zero current switches in every stage of the conversion process, causing dynamic losses to be close to zero.
B) Direct conversion from line AC to load DC in “one” step whereby all required end load DC voltages are drawn off from a common high frequency AC bus
By use of these two principals it is possible to achieve an overall system efficiency of over 90% resulting in a net energy savings of between 20-25%.
