| Abstract: | The rectifier power loss is the key factor limiting the efficiency of a low voltage switch mode power supply. The influences of synchronous rectifier driving method on power supply efficiency are analysed in this paper. It is proposed that higher efficiency may be obtained by using control driven synchronous rectifier than by using self driven synchronous rectifier. |
