About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Power Integrations Unveils High-Efficiency Quasi-Resonant PFC IC with 750 V GaN Switch

HiperPFS-5 ICs enable compact, efficient power-factor stage for ultra-fast adapters, consumer electronics, computer and appliance power supplies

APEC 2022 Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits (ICs) for energy-efficient power conversion, today announced the HiperPFS™-5 family of power-factor-correction (PFC) ICs with an integrated 750 V PowiGaN™ gallium-nitride switch. With efficiency of up to 98.3 percent, the new ICs deliver up to 240 W without a heat sink and can achieve a power factor of better than 0.98. HiperPFS-5 ICs are ideal for high-power USB PD adapters, TVs, game consoles, all-in-one computers and appliances.

Commented Edward Ong, senior product marketing manager at Power Integrations: “With OEMs and after-market suppliers racing to create the fastest, smallest, most versatile USB PD chargers for mobile devices, HiperPFS-5 ICs give engineers a critical advantage. We have combined our proprietary PowiGaN switch with a quasi-resonant, variable-frequency discontinuous mode boost PFC topology. By pairing HiperPFS-5 ICs with our new HiperLCS™2 chipset or our InnoSwitch™4-CZ active-clamp flyback ICs, designers can easily beat even the most aggressive efficiency regulations while cutting the bill of materials by half and achieving extremely attractive form factors for ultra-fast chargers.”

The capacitors and inductors used in power supplies generate a phase change between current and voltage, causing losses in the power lines and potentially disrupting other equipment connected to the AC mains. Many countries require power supplies over 75 W to adjust for this effect with so-called power factor correction, or PFC. While there are many PFC solutions available, HiperPFS-5 ICs with PowiGaN technology and a quasi-resonant (QR) control scheme represent the pinnacle of the art and science of off-line power quality enhancement.

HiperPFS-5’s innovative QR discontinuous conduction mode (DCM) control technique adjusts the switching frequency across output load, input line voltage and input line cycle. QR DCM control ensures low switching losses and permits the use of a low-cost boost diode. The variable frequency engine allows the reduction of boost inductor size by more than 50 percent compared to conventional critical-conduction-mode (CRM) boost PFC circuits. Low switching and conduction losses—which are further reinforced by the PowiGaN switch—together with lossless current sensing, mean that HiperPFS-5 ICs offer high efficiency across the entire load range, with efficiency rising as high as 98.3 percent. HiperPFS-5 ICs provide a PF higher than 0.98 at full load. At light loads an innovative power-factor-enhancement (PFE) feature compensates for input filter capacitance, maintaining a high PF of 0.96 even at 20 percent load. No-load power consumption is just 38 mW.

Other benefits accrue due to the robust 750 V PowiGaN switch. In many locations worldwide the mains' power can be highly unstable, often leading to over-voltage failure of power supply components. HiperPFS-5 ICs maintain a high power factor up to 305 VAC and can operate continuously at up to 460 VAC during line swells. Additionally, HiperPFS-5 ICs incorporate Power Integrations' automatic X-capacitor discharge (CAPZero™) function, including the required redundant pins to meet safety regulations, and high-voltage self-start-up—all in a low-profile, InSOP™-T28F SMD power package. Exposed cooling pads featured in the package are at source potential, providing effective cooling and simplifying the EMI solution. Digital line-peak-voltage detection ensures robust performance, even in the presence of distorted input from uninterruptable power supplies or generators.
