hi everyone
recently i have a project regarding controlling the rectified o/p voltage of an 3 phage alternator with varying load and rpm. the system parameters are as follows
controlled o/p = 130V
max o/p current = 0-200A
rpm = 0-2500 (0 - 500hz)
field current vary frm 0-10A to provide the desired o/p power.
i have to do this by varying the field current of the stator. the field voltage is get frm rectifying the two of the 3 phage. I want to control this by a microcontroller based PWM which ON/OFF the field voltage accordingly(varying field current) to maintain a constant voltage at o/p with varying loads. I design the h/w. A simplified block diagram is attached.
I need some topology(s/w based) to control this. any PI control code assistance.
if you need any further information please fill free.
thanks
