App note: Measuring inrush current

Sunday, January 28th, 2018

Inrush current evaluation from Aimtec. Link here In AC/DC power converters beyond a few watts, during the initial application of power an excessive inrush current will flow when the input capacitors are suddenly charged. If unhindered the inrush current can easily exceed 50 A at the peak of the AC...

App note: Limiting inrush current

Sunday, July 3rd, 2016

Aimtec's app note on inrush current on power converters and their solution. Link here Inrush currents can be problematic in circuits that utilize overload protection devices such as fuses and circuit breakers. The selection of overcurrent protection devices is made more complicated when high inrush currents are present. False overload...

App note: Forced air convection and heat sinking for power supplies

Sunday, July 3rd, 2016

Application note from Aimtec discusses about two ways for taking away heat on power supplies. Link here When evaluating the operating temperature ranges of power supplies one must consult component’s datasheets. Datasheets state a “usable” operating temperature range typically given at full output load. In order to reach the upper...

App note: Method to reduce the output ripple & noise of power supplies

Sunday, June 26th, 2016

Another app note from Aimtec on power supplies and how to minimize their output noises. Link here The switching power supplies have the fundamental advantage of high efficiency i.e. low power dissipation when compared to linear voltage regulation. However, there exists an important consideration concerning the presence of ripple and...
