Power Supply's Basic Configuration and Various Topology A variety of methods can be used for DC voltage conversion on the secondar y side, and among these are step-up, step-down, and polarity-inverting converters configured by changing the connections of diodes and choke coils. Some typical ways of using Renesas devices in step-up, step-down, and polarity-inverting converters are shown below. In particular, methods of supplying power in which conversion takes place adjacent to the load are called point of load (POL), and Renesas offers single-SiP solutions, SiP + power MOSFET solutions, and...

A power supply system for a large-format server comprises AC-DC converters, DC-DC converters, and point of load (POL) circuits. The AC-DC converters generate bus voltages ranging from 1 2V to 48V from the external AC, the DC-DC converters convert voltages of 1 2V to 48V to levels ranging from 5Vto 12V, and the POL circuits, each situated near its target load, supply the specific voltages required by individual loads. Renesas Electronics provides power devices optimized for each of these circuit types. Configuration of Server Power Supply SgiÜSÍDC/DCraffl Isolated DC/DC Power Supply...

Air Conditioners PFC The R2A20114A continuous conduction mode interleaved PFC circuit helps reduce costs in high-power applications such as air conditioners and has come to be used even in low-price models because it enables integral mounting of smaller boost coils and use of cheaper, general-purpose components with lower ratings. It has been widely adopted due to its combined advantages, including circuit stability at high power levels, phase dropping to boost efficiency at light loads and continuous conduction mode for low conduction loss at high power levels, and high efficiency over a...
