That is because blue light causes less diffraction at the same slot width compared to higher wavelengths, thus resulting in sharper imaging. Modern semiconductor processes provide small, shallow structures which can take advantage of the shorter penetration of blue light to improve efficiency. What’s more, smaller structures allow an interlaced photodiode layout which produces sine and cosine encoder signals with lower offset. In addition, a high fill-factor for the photosensitive areas is achieved by an equivalent geometrical transformation. iC‑Haus has optimized the new incremental scanners in its high resolution iC‑PT H‑Series especially for blue light, under the Encoder blue trademark. Delivered in a flat 5x5mm² optoQFN package, the chip requires a minimal scanning area of only 1.9x3.1mm to generate 10,000 pulses per revolution using a code disc of only 26mm in diameter. iC-Haus www.ichaus.com/encoder-blue Digital controllers for high-current PoL converters ZMDI (Dresden, Germany) has introduced its ZSPM1505/ZSPM1506 digital controller for powering high-current devices in sectors such as enterprise networking and storage equipment. ZSPM1505 and ZSPM1506 are single-phase true-digital power controllers for powering auxiliary power rails for field programmable gate arrays (FPGAs) in enterprise networking and storage applications. Many high performance FPGAs require a third power supply commonly referred to as the auxiliary rail (AUX). The AUX rail is often used to power internal clocks, phase-lock loops, peripheral input/output devices and transceivers in FPGA applications. These are critical rails that require tight tolerances and low jitter and ripple on the output voltages. ZSPM1505 and ZSPM1506 are pre-configured to provide a simple solution for high-performance, digitally controlled power supplies with one of ZMDI’s integrated MOSFET power stage DrMOS products: the ZSPM9000, ZSPM9010, ZSPM9015 or ZSPM9060. ZMDI www.zmdi.com Passive harmonic filters clean 200-240VAC power lines A line of power-quality-improvement products from Schaffner, under the name ECOsine, has been augmented with further passive harmonic filters, for applications in the voltage range of 200V to 240VAC. These filters, FN 3416LV (50 Hz) and FN 3418LV (60 Hz), extend the application range of the ECOsine Economy Line down to 200 V to 240 VAC and offer a cost-effective solution for harmonics mitigation particularly suitable for applications requiring superior THDi performance and with limited available space. Both new series are intended to be used for harmonic mitigation of three-phase installations with diode or thyristor bridge interfaces, enabling to achieve a target THDi of under 7% in presence of a DC-link inductor. Both rectifier peak current and RMS input current are reduced and the grid current is restored to its sinusoidal shape. Lower electrical losses and improved power factor allow an enhanced and more efficient utilisation of electrical system capacity. The filter concept allows for a quick installation and commissioning without the need of thorough system analysis and the involvement of specialists.
