The design utilizes Power Integrations' HiperPLC power supply controller, which enables a simple, cost-effective circuit design by combining power factor correction (PFC) and resonant (LLC) control functions on a single integrated circuit. The new design will be showcased in the Power Integrations booth at LED Expo Korea (Kintex, Korea; May 20-23) and LED Lighting Taiwan (Taipei, Taiwan; June 10-12).LEDs are rapidly emerging as the preferred streetlighting technology, displacing traditional technologies such as high pressure sodium (HPS) lamps.
HiperPLC, Power Integrations' first high-power product, is designed to control AC-DC converters from 80 to 600 watts. HiperPLC minimizes costs by reducing the size of the PFC magnetics required, and by combining the PFC and LLC controllers into a single IC. The IC provides up to 0.99 power factor and features synchronization of PFC and LLC controllers. Synchronization reduces the ripple in the bulk capacitors, which reduces capacitor operating temperature and significantly extends the life of the power supply. Support for HiperPLC is now featured in Power Integrations' PI Expert software, an automated power supply design tool based on PI products.
Comments Doug Bailey, Power led high bay light vice president of marketing: "Municipalities around the world are finding that LEDs offer a greener, more economical approach to streetlighting by saving both energy and maintenance costs. However, these benefits cannot be fully realized without a highly efficient, reliable power supply driving the LEDs. With HiperPLC, designers can produce a simple, reliable, cost-effective, power supply with efficiency as high as 92%.Power Integrations is the leading supplier of high-voltage analog integrated circuits used in energy-efficient power conversion. The company's innovative technology enables compact, energy-efficient power supplies in a wide range of electronic products, in AC-DC, DC-DC and LED lighting applications. Since its introduction in 1998, Power Integrations' EcoSmart(R) energy-efficiency technology has saved an estimated $3.4 billion of standby energy waste and prevented millions of tons of CO2 emissions.
