Hydrogenics Signs with China's Largest Energy Companies

Hydrogenics Corporation (TSX:HYG, NASDAQ:HYGS), a developer and manufacturer of hydrogen and fuel cell systems, has received orders to supply electrolysis-based hydrogen generator plants to two of China’s largest energy companies. China Electric Power Energy Group and China National Power have each purchased a HySTAT-A Hydrogen Plant, capable of producing 10 Nm3/h of high purity hydrogen at a pressure of 25 bar. In both cases, the hydrogen produced will be used to cool the generators in a coal-fired power plant. Delivery of both orders is expected to take place in 2006. “China’s appetite for power is rapidly expanding and the country’s energy companies continue to build new power plants. This is a growing market today for our world-leading onsite hydrogen products,” said Pierre Rivard, Hydrogenics President and Chief Executive Officer. “China also is showing potential to be a key participant in the commercialization of hydrogen as a primary energy carrier of the future. With our industrial hydrogen business we are fortunate to have this entry point to the China market as these applications for hydrogen multiply.” Hydrogenics was awarded the contacts after a rigorous public bidding process that focused heavily on safety and reliability. China Electric Power Energy Group and China […]

Power Integrations Introduces Industry-First Integrated Switcher IC Family

Power Integrations (NASDAQ:POWI) has introduced PeakSwitch(TM), a new family of ICs for power supplies with peak-to-continuous power ratios of up to 3:1. The industry’s first monolithic power-conversion IC with peak-mode operation, PeakSwitch enables highly integrated, energy-efficient power supplies for applications such as printers, personal video recorders (PVRs), audio amplifiers, broadband modems and DC motor drives. “Until now, power supplies had to be over-engineered to accommodate high levels of peak power use,” said Balu Balakrishnan, president and CEO of Power Integrations. “With PeakSwitch, designs only need to accommodate a power supply’s continuous power requirements. As a result, designers can use smaller transformers and other components, resulting in a lower-cost power supply.” Printers — an ideal application for PeakSwitch — require steep, momentary spikes in power delivery when a print job is initiated. For example, an inkjet printer that operates at a continuous level of 30 W during printing might require a burst of up to 80 W in order to activate the paper-advance motor. PeakSwitch supplies this burst by automatically increasing the switching frequency of the IC’s integrated MOSFET for several milliseconds before returning to continuous-mode operation. This approach allows the use of transformers, capacitors and other components sized for the […]
