Common European framework, long-term national objectives and problems the branch development is facingDuring the last several years investment interest in wind power engineering in Bulgaria has been continuously increasing. A number of factors contribute to the development of this branch, among which the EU policy on increasing the share of electricity generated from renewable energy resources and accompanying programs for renewable energy resource projects subsidizing. The active legislation and statutory instruments in Bulgaria in this field also contribute as they ... more

DSCs are replacing analogue PWM controllers to bring new levels of flexibility and cost reductions for intelligent power supplies.Bryan Kris,Microchip TechnologyMarket factors are driving the development of intelligent power supplies that involve external control of the power supply and soft configuration in production. One way to achieve this is with digital feedback control of the power-conversion loop. Power-supply designers have employed microcontrollers (MCUs) in intelligent power supplies for communications, monitoring, control and deterministic functions, such as power sequencing, soft start ... more

Recent developments in Croatian biofuels industryVelimir Segon, Researcher, Energy Institute Hrvoje Pozar, CroatiaVelimir SegonAfter almost 15 years of continuos promotion of biofuels benefits and recent and still ongoing rapid development of biofuels industry in almost every European country, first amounts of biofuels are finally to be produced in Croatia. Croatia is a country with very limited fossil fuel resources. Around two third of the consumption has to be imported. Of these petroleum products needs, diesel fuel consumption for the transport ... more

Future-proofing embedded automotive systemsMaking the right microcontroller architecture choose can reduce development costs and future-proof automotive embedded systems developmentDan Termer, Vice President, Vertical Markets Group, Microchip TechnologyThe automotive electronics industry continues to expand its usage of 8- and 16-bit microcontrollers (MCUs). As the MCU is the cornerstone of electronic control modules (ECMs), from safety to convenience systems, and from chassis and driver information to security systems, the selection of the appropriate 8- or 16-bit MCU supplier is critical for the ... more

The current picture of South-Eastern European (S.E.E.) biomass energy marketBy Giacomo BizzarriThe continuous changes in the composition of European Union (E.U.) imply continuous focuses on some major markets of common relevance. Biomass energy market is indeed one of these. The potential of the various biomass sources is evaluated through an analysis that focuses especially on the opportunities still unexploited. By providing detailed knowledge of some national strategies and policies on biomass energy, the study aims at enabling a better estimation ... more

Appliance designers can now take advantage of the latest Digital Signal Controllers (DSCs), such as Microchip’s dsPIC33F motor-control family, to improve energy efficiency and cost savings in motor systemsJorge ZambadaMicrochip TechnologyGiven that motor-driven equipment, including motors, pumps and fans, can account for 64 percent of the electricity consumption, improvements to motor systems could result in dramatic savings in energy and cost. The Brushless DC (BLDC) motor is used in both consumer and industrial applications, owing to its compact size, controllability ... more

Deeply embedded applications can now enjoy leading edge processing power, thanks to 32bit developments in microcontrollers.Coming from a background of desktop applications, it would seem strange to consider using a processor that offers anything less than leading edge performance. For an engineer more entrenched in embedded applications, processing power has always been measured not just against the benefits it brings but by the resources it consumes.Within the embedded domain, the irresistible force that is ‘faster, smaller, cheaper’ has always been ... more

Electronics industry in Bulgaria has long standing traditions and highly-qualified, experienced work force. It’s generally export oriented - 75% exports. Main markets served are automotive, telecommunications and consumer electronics. The good level of expertise in multimedia solutions, microwave communication, fiscal memory electronic devices and electronic energy meters attracted over 180 million USD foreign investments. Most of the electronics producers have quality management systems applied – ISO 9000, ISO 16949. Up-to-date manufacturing technologies, high level of the production ranges and the ... more

by Bonnie C. Baker, Microchip Technology Inc.Often, analogue-to-digital converter users employ averaging algorithms with their controller or processor on the output of several samples from the converter. A converted signal can be smoothed by using this technique (see Figure 1), and the effective resolution can be improved by reducing system noise.Smoothing converted dataThe smoothing effect on the converted data is implemented by acquiring multiple signals at a constant sample rate, averaging a predetermined group or number of the samples, and ... more

Kevin Tretter,Microchip Technology Inc.The world of data acquisition is extremely diverse, encompassing measurements of temperature, pressure, humidity, strain and a variety of other physical phenomenon. In addition, these measurements may be required under harsh conditions, such as extreme temperatures, centrifugal forces and electrically noisy environments. System designers must be diligent in not only selecting the correct sensor for their application, but also in designing appropriate signal conditioning to deal with these issues. This article will focus on the signal conditioning ... more

Gaurang Kavaiya,Microchip Technology Inc.From the early days, the ‘mantra’ for the semiconductor industry has been “Smaller, Better, Faster and Cheaper”. The current Pocket PCs are more powerful than the first computer, which required a separate building. The way this goal has been achieved, so far, is to reduce the size of the individual transistor used to create the semiconductor device. This has an interesting side effect. As the transistor gets smaller, the operating voltage gets lower. The 5V power-supply rail ... more

Lucio Di Jasio, Microchip Technology Inc.Switch-Mode Power Supplies (SMPS) are traditionally implemented using a basic analogue control loop. Recently, advances in Digital Signal Controllers (DSCs) have enabled designs where full digital control schemes begin to become practical and economical. Still, early adopters of digital technology are expected to be at the high-end of the applications spectrum, where the benefits of full digital control are the most immediate. However, there are a large number of applications that can greatly benefit from ... more
