Telecommunications/servers, and general-purpose power supplies with up to 43-WĪC/DC converters based on gallium nitride (GaN) from Power Integrations offer up to 95% efficiency at full load. Power supply for household appliances (e.g., washing machines, refrigerators,Īnd air conditioning), set-top boxes, LCD/LED monitors, Intended for switch-mode power supply (SMPS) applications such as an auxiliary Modulation (PWM) controller to optimize the variation of the switchingįrequency under different AC line input working conditions. The latest generation of AC/DC CoolSET integrated power stages from Infineon Technologies AG is made possible by the integration of its latest family of CoolMOS P7 700-V and 800-V superjunction MOSFETs in both DIP-Package 7 and DSO-12.ĬoolSET series, integrated with an intelligent digital algorithm, allows the pulse-width These features result in a drastic reduction in size, increased reliability, and superior energy savings in industrial applications. The device improves energy efficiency by 5% (and reduces power loss by 28%). Plus heat sink to a single IC) thanks to the integrated SiC MOSFET and The number of parts required compared to conventional designs (from 12 parts Problems encountered by designers using discrete solutions. The use of low-voltage SiC MOSFETs and IGBTs limits the amount of energy savings in the auxiliary power supply.įacilitates the efficient design of AC/DC converters by solving many of the The series integrates a 1,700-V SiC MOSFET, providing greater energy efficiency, miniaturization, and higher voltage capacity than existing silicon power devices. ROHM Semiconductor’s BM2SCQ12xT-LBZ series of AC/DC converters are optimized for industrial applications, including inverters used in high-power equipment. 1: The RECOM RAC04-K/277 series (Image: RECOM) Outputs and a wide margin to Class B emissions compliance without externalĬomponents, which make them easy to install ( Fig. In addition, the modules provide an input voltage range from 80 VAC to 305 VAC for all territorial requirements.ĪC/DC modules also offer a reinforced Class II isolation rating for floating The modules offer a peak load capacity of up to 150% for dynamic power requirements. Offering a 4-kV insulation and operating temperature from –40☌ to 90☌ make them suitable for a wide range of operating conditions. One example is the most recent addition to RECOM Power GmbH’s low-power AC/DC portfolio, the RAC04-K/277 modules for domestic and ITE applications. Reduces the variability of design error and permits robustness and parametric The use of highly integrated AC/DC converters Is always subject to variability, but a well-designed system must provide This canīe achieved through innovative processes and technologies such as silicon carbide Very often, to meet specific requirements, a highly integrated solution usuallyĭelivers higher performance and lower power consumption than discreteĬonverter usually requires good switching for high energy efficiency. Voltage, and overvoltage), and temperature (overheating and ambient temperature (overvoltage and input voltage drops), output (overload, short-circuit, reverse There are several types of protection, including those related to input Topology, control algorithm, and performance are just some of the critical aspects.įunctions are also an essential safety and reliability aspect in a power system. The selection of an AC/DC controller is related to several factors. Incorporate innovative features and cut development time. The industry offers an increasing number of integrated circuits that Nodes, actuators, and low-power “always on” sensors.ĭevelopment and choice of an AC/DC converter can become a real challenge. Smart homes and smart offices need mesh control systems with many Home, for example, power devices implement efficient hardware for AC/DCĬonversion with the aim of mitigating energy losses and achieving significantĬost savings. AC/DC converters are mainly used in consumer devices, medical devices, industrial and process control systems, measurement equipment, semiconductor manufacturing equipment, and defense applications. The AC/DC converter aims to convert the input AC signal into a variable DC voltage and then optimize it through a filter to obtain an unregulated DC voltage.
