Hello,

the explanation at your question is not so straightforward!

There is a lot of concepts related to apply PWM either on high or and low side.

Fortunately for you, there is also a lot of documentation that explains everything.

So, I advice you to address the following URL:

and donwload the following ANs:

AN1946, AN2030, AN2009, AN1905.

After your reading, all should be more clear. If not, please, contact again the forum for further explanations.

Best regards,

I'm a student and i'm working on BLDC motors, could

you explain me advantage and disavantage of controlling BLDC motor

by appling PWM signal on high side of MOSFET transitsors

or by appling PWM signal on low side of MOSFET transisors

or by appling PWM signal on both side of MOSFET transistors

Thanks for your help

Best regards
