First post for me and I am looking for some guidance or perhaps a product that can meet my requirement. I manufacture hydraulically driven ac generators and at present use a mechanical flow control valve to maintain constant droven speed of the ac alternator, for most applications the flow regulation with a mechanical valve is suffice but more often now I am being asked for more precise regulation of the speed of the alternator and to achieve this I need to use a proportional valve, which are readily available, but what I need to do is convert the 50Hz AC generator frequency to a control current for the proportional valve such that the valve maintains constant flow irrespective of load, temperature etc.
I'm not an expert in this field but wondered if there was a simple solution for this, my valve has a threshold current of 800ma and a maximum control current 1600ma at 12vdc, for the alternator to operate at a constant 50hz, 3000 rpm I need to maintain a constant control signal of approx. 70% of 1600ma, 1120 ma.
This might be a bit vague so feel free to ask any question that will help you in anyway
