      Compact Vehicle Power Systems Users of power control equipment have used third-party systems for many years, because they offer the benefits of reduced development costs, shorter time to market and ease of meeting qualification standards. As specifications have become more demanding, it has become necessary to use higher levels of integration, with [...]

      Using an Intelligent Power Management Solution In today’s consumer electronics marketplace, it’s become increasingly difficult to separate different classes of products. Users now demand more from their mobile phones than simply making and receiving calls, and their portable navigation devices (PNDs) need to do more than just get them from point A [...]

      Low power application example: Solar reader The Corporate Publishing division of a large German publisher has received an order to develop a customer magazine on the topic of sustainability for a management consultancy firm. For a small exclusive share of the circulation (approx. 700 copies), which the management consultancy firm will use [...]

      The temperature increase of the case is moderate High integration of power electronic systems requires optimized packages. This paper presents an innovative, fully-molded intelligent power module for small power three phase drives in a dual-in-line package. The package itself offers the possibility of integrating additionally the input bridge rectifier. The article discusses [...]

      This could form the basis where high performance is not required This article focuses on a minimal resource microcontroller implementation for a 3 phase BLDC motor, closed loop speed motor controller application based on a Microchip PIC12 device. It shows how minimisation techniques can reduce the number of I/O pins to just [...]

      With the information about the temperature, digital signal correction is improved remarkably In the field of power efficient solutions, the precise knowledge about the flow of electrical power over a broad spectrum is indispensable. Without this knowledge, no decision could be taken about how to save electrical power without loss of functionality [...]

      It is important to have more than four measurement channels High-speed inverters incorporating faster, higher-voltage devices are increasingly being used in areas such as transport – both automotive and rail – and renewable energy including solar and wind power. R&D laboratories devoted to such products are seeking higher performance while reducing development [...]

      Ultralow EMI DC/DC Regulator System Meets EN55022 Class B Standard Systems incorporating sophisticated high frequency functionality are consuming more power and are increasingly assembled on denser circuit boards. Higher power consumption and close proximity of components increase the risk of point-of-load switching regulator’s electromagnetic energy interfering with RF circuitry. By Afshin Odabaee, [...]
