Hi,
I am developing a bldc motor controller and is in the starting stage.In one of the design file , i have seen the input stages are as follows: supply, emi filter, boost converter, phase shifted full bridge converter, synchronous rectifer and then comes the inverter. My doubt is why cant we directly give the boost converter output to inverter.
The thing is that i need two levels of voltage to be fed to the motor. i.e, 90V and 230V. How can i do this without manually adjusting anything also that should be done without stopping motor?. Is synchronous rectifier and full bridge converter is required for this purpose?
Thankfully,
Agnes
