Most data sheets will offer a figure for efficiency allowing the user to quantify the waste heat generated within the end equipment. The efficiency of a power supply will vary dependant on the load and input voltage applied, so it is important to understand the units efficiency under the operating conditions of the application. Efficiency during operation at low line is typically lower than at high line and may vary by as much as 6-7%. The most important parameter is the worst case efficiency in order to understand the maximum waste heat generation by the supply. The drive in power supply development is to increase efficiency in order to reduce the physical size of the product and reduce power consumption. This is also being driven by the standby/no load power and average active efficiency requirements set out in legislation such as Energy Star, CEC, EISA and EUP. Power density specifications are being increasingly used by power supply and dc/dc converter manufacturers to convey advancement in power technology & efficiency. If these watts per cubic inch specifications are compared it is essential to ensure that the products have similar specifications and do not require external components to meet various specification requirements. |
