Embrace the switching power supply technology and market changes

Power inverter manufacturers electric Shenglan (Densei-Lambda) in Beijing recently announced the launch of the fifth generation of switching power inverter products to meet the industry of environmental protection (in accordance with the EU RoHS Directive), the needs of small, high efficiency switching power inverter products. Meeting, Densei-Lambda has introduced a series of four new power products, new models. Including two fifth-generation new product --AC/DC standard switching power inverter HWS series and CC-E series of DC / DC converter; 1,500 W power industry's first 1U size small large-capacity the CVCC variable power Genesys series; and an emphasis on cost-effective package type AC / DC power inverter SWS series.

, HWS series is an output power of 15W, 500W, the output voltage of 3.3V-48V efficient small products. It is reported that, compared with older products, HWS series at the same time ensure that the same output power is reduced 50% by volume. Rich lineup of the series, package type, non-encapsulated form, select the remote control type applications include factory automation equipment controllers, semiconductor manufacturing / inspection equipment, medical equipment, electrical equipment and a variety of display devices. CC-E series is a small, lightweight, RoHS compliant DC / DC converter products, do not use tantalum capacitors and electrolytic capacitors, a full range of built-in remote control function the corresponding DIP and SMD assembly methods, the output voltage accuracy (± 3%).

Yamagami Wu, Sheng Miranda overseas marketing manager, said: "Our products are using the latest technology, the full realization of the lead-free process, most of the products have to meet soon to implement the RoHS Directive, shows that we have to go in the environmental the forefront of technology. "

Wuxi Meilan Electronics Co., Ltd. Technology R & D Manager Huang Ting said, the standard switching power converter , was born in the early 1970s, the second generation of switching power converter products for the mid-1970s to obtain UL certification, third generation switching power inverter products for the mid-1980s, in line with global specifications, the fourth generation of the mid-1990s to meet the harmonic current suppression regulations and EMC requirements of switching power converter. With the imminent entry into force of the EU environmental directives (RoHS) RoHS compliant, saving energy and low noise, the fifth generation of environmentally friendly special switching power inverter began to appear around 2005.

 In recent years, with the DSP, such as the miniaturization of components, high-speed, the control portion of the switching power converter is the direction of digitization development. Due to digital, so that the intelligence of the switching power inverter control section, and the remote monitoring of the operation state of the components in common, and the power inverter becomes possible. Switching power converter market, in terms of quality, delivery date, standard power is growing stronger. However, the method of use of the power inverter system is different different, the existing situation is that a very strong demand for special power. Digital control of switching power converter set the standard power and special power advantages in one, has become the focus of attention of the industry. Papers and electric Shenglan in the development of the digital power invested a lot of manpower, its advanced development project leadership bamboo Eiji is also due to be called the "the digital PWM decomposition can improve the method of the Japan Electronics and Information and Communication Engineers communication energy technologies The studies will be awarded the "the young engineers Papers Award".

Bamboo on Eiji pointed out: "The digital power is the most critical is the cost of the expected widespread use after three years, is currently a lot of companies still in development stage." He said, because the cost is still high, the main application of digital power technology those who need a lot of features, flexibility and cost sensitive applications, such as robotics, high-precision color display of large display high watt variable power inverter with charger and communication small DC / DC converter.

 For switching power inverter with charger industry, not just technically, is experiencing a major change, and the industry is also taking place in the integration, mergers and acquisitions frequently occur, Densei-Lambda also involved which. In 2004, C & D Technologies has acquired Celab, Datel and Celestica power inverter with charger, the three companies. In 2005, TDK announced $ 235 million acquisition of the British Invensys plc's the Lambda power companies, including Lambda USA, Lambda Europe, Densei-Lambda KK, and several other entities. Subsequently, Densei-Lambda Lambda USA, Lambda Europe announced that it would integrate its, Densei-Lambda TDK subsidiary. Recently, TDK and Densei-Lambda announced after April 1, 2006, power products enabled unified brand TDK-Lambda covering AC / DC switching power supplies, DC / DC converters, DC / AC inverter and power inverter with charger modules, etc. products, the two sides will jointly promote and sell.
