Compared with BEC with linear regulation, the advantages of BEC with switching power supply are mainly reflected in:
1. When using more than 3 strings (11.1V) batteries, it can greatly reduce BEC heating and improve the overall efficiency. (For example, when using 4 strings of lithium batteries, the voltage is about 14.8V during normal use.)
2. Using the transmission linear voltage regulation method, In order to output a current of 5V/1A, a current of 1A must also be input to the power supply side. Therefore, there will be 14.8V×1A= 14.8W power consumption on the BEC, but the actual useful output of the BEC is only 5V×1A=5W, so the overall efficiency is only 5/14.8= 33.8%, and the other 9.8W power consumption is converted into heat, so it will cause the BEC to overheat, and the chip will enter the protection state and cannot work; Using the switching power supply method, to output a current of 5V/1A, our actual test shows that only 0.38A of current needs to be input on the power supply side, that is, 14.8V×0.38A= 5.6W of power, so the overall efficiency is 5/5.6=89.3%.
