What is a -48V back-up battery converter?The -48V back-up battery converter is similar in construction and complexity to the single-output, high-power VoIP converter previously discussed. The power factor corrected (PFC) AC/DC produces the supply voltage for the 3G Base station's RF Power amplifier (typ. +27V) and the bus voltage for point-of-load converters.
What is a 3G base station converter?In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.
What voltage does a DSL power system supply?The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5V).
What is a multi-output power supply design?Multiple output designs may also employ a complex regulation scheme which senses multiple outputs to control the feedback loop. Voice-over-Internet-Protocol (VoIP), Digital Subscriber Line (DSL), and Third-generation (3G) base stations all necessitate varying degrees of complexity in power supply design.
How is a 27V DC bus voltage generated?A 27V DC bus voltage is generated using a dual FET forward converter. This forward converter has two upper FETs, each connected to a primary winding with the appropriate number of turns on the power transformer.
How to choose a power supply topology for a multi-output DSL converter?Selection criteria for the power supply topology in multi-output DSL converters include requirements for performance (high efficiency and tight load and line regulation), simplicity, low cost and a small footprint with a low profile. High performance is achieved by selecting the appropriate topology and control circu
