Generation and Regulation
Signal’s efforts in the sector of energy generation and energy saving can be found in a series of already developed solutions here described.
Management of micro-generators that use air or water flow to generate energy between 1W to a few tens of Watts. Small conduit water flow applications were developed (for home use as well as industrial) and for compressed air recovered from drains. With these, energy can be obtained from free sources without any external connection.
Within this field, Signal not only designs the electronics, but also the generators, while also dealing with problems related to optimal use. *
Another innovative is the control and tele-control of microgenerators of compressed air, moved directly by wind energy. This solution is unique as it is self-sustaining and thus independent from any external power supply.
The tower control is powered by the wind, and it calculates the working conditions, ready to block the rotor in any case of danger. Moreover, it measures the quantity of air generated and any potential long-term damages.
All the data collected is sent via radio to the main console where they can be visualized.
More similar micro-harvesting solutions are being developed from bender and magnetic piezoceramics.
Starting from the well known and reliable magnetic regulators buck-boost, Signal developed an electronic version that is much more flexible.
With this technology it is possible to create mono and triphasic alternate voltage regulators ranging from a few hundred watts to a few megawatts. The yield is close to 100% (98%), no distortions or harmonics are introduced, and the special structure makes it fault-tolerant.
Output voltage is guaranteed even in the case of electronic failure.
Voltage and output power can thus be controlled with various rules from the application (hourly tables, based on external measures, tele-controlled even via mobile connection)
Typical uses are in the regulation of light flow for pre-existent machinery with HID lamps in which energy usage can be reduced up to 40%, with an average reduction of 15-20%.
Other widespread applications are to limit power peaks due to network fluctuations.
