In recent interviews, frequently encountered this problem, really didn't study, who to guidance!

CodePudding user response:

Electronic circuit without power supply, switching power supply has advantages of clear, principle must understand, is the basic principle of inductance current not mutations in because of high frequency can be reduced volume, compared with the original use of low frequency transformer, occupied area is small, light weight

CodePudding user response:

Buck boost topology and basic principle

CodePudding user response:

Really ah, I also met, asked the switching power supply, buck circuit

CodePudding user response:

Power energy transformation way, from this Angle to understand

CodePudding user response:

Switching power supply with high efficiency, small size, light in weight

CodePudding user response:

Step-up step-down principle, energy efficiency and frequency relation, inductor, transformer design, these all don't understand, how do you intend to interview after mixing?
