Layer Electronics, which is still aiming for continuous development, has developed a project along with the ENEA – Agenzia nazionale per le nuove tecnologie, l’energia e lo sviluppo economico sostenibile (Italian National Agency for New Technologies, Energy and Sustainable Economic Development) and the DIEETCAM of the University of Palermo: a prototype of bi-directional converter completely controlled by DSP, fed by renewable energy sources (solar, wind, …) and by a storage system (lead-acid, NiCd, Li-Ion, NaNiCl2).

The conversion system is able to perform actions of local control, and to respond to remote control signals in order to:

Contribute to processes of regulation of the voltage and frequency of the electrical system in grid connection;

Support the voltage and frequency, maintaining their values within predetermined ranges of variation in stand-alone;

Keep adequate power quality indices in all the operating conditions.


According to the needs, the Aton storage converter will work as:

a grid connected inverter from a storage system (lead-acid, NiCd, Li-Ion, NaNiCl2);

an off-grid inverter from a storage system (lead-acid, NiCd, Li-Ion, NaNiCl2) to supply loads during a blackout (the so-called “UPS mode”);

a Power Factor Correction (PFC) charger from mains to recharge the storage system (lead-acid, NiCd, Li-Ion, NaNiCl2).

The Aton series of storage bi-directional converters represents the state-of-the-art in quality and technology, accumulated by LAYER ELECTRONICS in 50 years of experience in the field of the stabilization and static conversion of the energy.

This bi-directional converter will be available shortly.

Less than 1 kVA UPS segment is expected to continue dominating the global UPS market, in volume terms, during the forecast period, due to growing usage of these UPS types among diverse end-user segments. Below 1 kVA UPS is primarily installed with desktop PCs to provide back power to the system. Moreover, UPS with less than 1 kVA rating are more cost effective than other UPS types, which is leading to their higher adoption. The market for less than 1 kVA UPS is expected to grow significantly during the forecast period, in terms of value as well as volume, largely driven by growth in the IT/ITeS and SMB markets, globally.

According to TechSci Research report “Global UPS Market Forecast & Opportunities, 2019″, the global market for UPS is forecast to grow at a CAGR of about 8% during 2014-19. Amongst all regions, Asia-Pacific currently accounts for the largest share in the global UPS market due to expanding infrastructure coupled with growing commercial markets such as IT/ITeS, retail and hospitality. Growth of unorganized players, especially in low rating UPS segment, is emerging as a major challenge for the organized players operating in the global UPS market. The unorganized sector continues to maintain its stronghold despite large-scale efforts by leading players to launch high-value entry level UPS solutions. This is majorly due to growing UPS sales in Small Office/Home Office (SOHO) and SMB markets, which are largely driven by consumer-vendor relationships, thus benefitting unorganized players in the long-term.

=Global Power Electronics market 11 June 2015

In 2014 the global market for power electronics was worth $10.6 billion. The controlled power electronics segment reached almost $6.6 billion in that year and should increase to $7 billion in 2015. Market research shows that the segment should reach approximately $10.1 billion in 2019, revealing a CAGR of 7.4% from 2014 to 2019. Silicon will remain predominant with an 87% share, but new SiC and GaN technologies will be the fastest-growing – at 30% and 32% annual rates respectively, says Lux Research.

Power electronics is an enabling technology. It is the basis of many complex systems, determining their efficiency in an increasingly competitive industry. The power electronics industry in fact is primarily focused on identifying new materials that will satisfy user demand for superior performance, at the least incremental pricing. Silicon, a material that has been at the centre of power electronics, is now becoming inadequate to further the evolution of products in line with consumer demand. Consumer electronics and IT will account for 48% of the market by 2024. Stakeholders are therefore searching for alternative and innovative materials to meet the demands of the power electronics industry. Compound semiconductors so far seem to provide an effective solution for the advancement of power electronics. In fact, their wide-bandgap characteristics make for superior thermal management on one hand, and better frequency response on the other. This results in more efficient, smaller and cheaper power electronics.

The drive of the power electronics market so far has been the increase of power electronics in utility applications, which was previously hindered by the high cost of power electronics devices and the need for energy conservation. The challenge which the market is facing today breaks down to a gradual introduction of new materials and related processes without greatly upsetting the status quo.

=The Dynamics of Renewable Energy Inverters Market 21 April 2015

According to a new report from Pike Research, the market for inverters for renewable energy applications totalled $7 billion in 2014. That figure will more than double over the next 4 years, surpassing $19 billion in 2017.

Inverters companies must increase functionality, reduce cost, and differentiate themselves from the growing competition.

Over the next several years, Europe will continue to be the leading market for renewable energy inverters, accounting for 43% of all renewable energy inverter capacity installed through 2017, led by solar photovoltaic (PV) inverters. Meanwhile, 72 GW of renewable energy inverters will be installed in the Asia-Pacific region, compared to North America’s 66 GW. In all, nearly 290 GW of vendor-supplied inverter capacity will be installed worldwide across four primary technologies: solar PV, small wind power, stationary fuel cells and vehicle-to-grid (V2G) enabled vehicles – between 2013 and 2017.

The PV industry rarely remains static for long. Since PV became a mainstream technology, the industry had done everything – grown, declined, changed – at a frantic pace. The solar inverter market is no exception to this, and has also been subject to major changes since it became a billion-dollar industry over seven years ago. In 2013, the PV inverter market was characterised by big declines in pricing, a radical change in the regional make-up of the industry and some big shifts in top-ten supplier rankings.

Power ranges of frequency converters (micro power converters, low power converters, medium power converters, and high power converters) and voltage ranges of frequency converters (low voltage converters and medium voltage converters) are identified and included.

=Electronic voltage stabilizers 31 January 2015

The SE electronic voltage stabilizers are designed for continuous operation and guarantee maximum reliability and minimum maintenance, and have been offered in our production range for more than forty years.

The SE stabilizers are products called ”electronic”, because both the control and the regulation system are purely electronic.

Our stabilizers take advantage of the principle of the series transformer to increase or to decrease the value of the input voltage in a gradual and rapid way through the secondary winding in series of a transformer supplied by power triacs and controlled by an electronic board with microprocessor at high speed.

The principle of the stabilization in alternating current is to add or to subtract to mains voltage a voltage with the same frequency and in-phase or out-of-phase (180°), always taken by the mains, in order to turn back the output voltage within the planned range. The supplying voltage of the series transformer is given by power triacs, driven by an electronic board that, constantly verifying the value of the output voltage, provides to supply the series transformer up to the attainment of the nominal voltage.

So far SE stabilizers have been installed in several African Countries, like Nigeria and Angola, to stabilize voltage coming from power stations very far from towns or villages, which use that energy.
