i am working on a project, it involves 100VDC Motor and i want to drive this motor on mains voltage, so my plan is to convert 220VAC to ≈ 308VDC using rectifier, then using mosfet control by pwm signal ≈ 40% duty cycle to drive my 100vdc motor (using capacitor to filter the DC voltage), my query was is this possible. if not what are the alternatives?
