| Abstract: | KA3525 is a kind of PWM control component.In order to achieve high efficiency,its output square-wave pulse is used to drive the inventor electric circuit to work so that the output power component can be put in an on-off state.In addition,the paper introduces the functions of inversion circuit and the working model of controlling and charging.The mechanism of inversion component's high efficiency is addressed.The experiment has proved that the proposed circuit is not only of high efficiency,practical and easy to operate,but also can extend the battery's service life. |
