Ac To Dc Converter Efficiency
An ac dc converter usually requires good switching for high energy efficiency.
Ac to dc converter efficiency. A power converter s efficiency ac dc or dc dc is determined by comparing its input power to its output power. With ac dc system efficiencies averaging around 65 and dc dc system efficiencies at 80 it is understandable that more weight has been placed on ac dc. Most dc to dc converter circuits also regulate the output voltage. The xl375 ac dc supply from n2power is rated at 375 w with forced air cooling.
With a vast array of power supplies to choose from xp power has created an easy to use selector tool to quickly narrow down to the. This fully tested reference design is a high efficiency high power density ac dc adapter solution with a wide input voltage range 100 to 240 v ac for laptop adapters and smartphone charger applications. Our green power range focusses on high active mode efficiency and low no load power consumption complying with the latest global energy efficiency standards. It s also specified as a 260 w unit designated the xl350cc with passive convection only cooling which is.
It impacts the thermal and electrical losses in the system as well as. Choosing an ac dc power supply or ac dc converter. More precisely the efficiency of the converter is calculated by dividing the output power pout by its input power pin. If you only look at the inverter losses you would lose about 30 in a 95 efficiency inverter.
Some exceptions include high efficiency led power sources which are a kind of dc to dc converter that regulates the current through the leds and simple charge pumps which double or triple the output voltage. Each device is always subject to variability but a well designed system must provide robustness to these margins. The greek symbol eta η is usually used to represent efficiency here is the formula for. Efficiency is an important dc dc converter characteristic particularly for virtually every battery based or embedded system.
The bm2pxxx series encompassing a total of 24 models with an internal output power transistor and most protective functions delivers high efficiency surpassing the new 6 0 version of energy star while offering an extremely small profile. This is because a 95 efficiency inverter has a maximum efficiency of 95 only if the load and the input power and all parameters are perfectly matched.
