Abstract: A high-quality switching power supply efficiency is as high as 95%, and the switching power supply loss is mostly from switching devices (MOSFETs and diodes), so the correct measurement of switching device losses is critical for efficiency analysis. So how do we accurately measure switching losses? First, switching loss Since the switch is a non-ideal device, its working process can be divided into four states, as shown in Figure 1. "On state" means that the switch tube is in the on state; "off state" means that the switch tube is in the off state; "on process" -
I’m designing a hand-held device for a client, and I’m in need of a membrane switch keypad. One of the requirements is that the keypad be manufactured to withstand moisture. Do you know any companies who specialize in very tough keypads for rigorous environments? -
I used a switching power supply(300v, 24w), why can't it bear a 240w circuit ? (240w is a certain number of 2.4w loads in parallel )
