How to increase or decrease the frequency of AC current linearly? Suggest me some ideas
Would a circuit that continuously reverses the polarity of a DC supply do what you want? It would have a control that varies the rate at which polarity reverses. How often do you want the polarity to reverse? Maximum rate, minimum rate?I want to switch the poles of an electromagnet using a AC power supply... In Order to control the switching speed I would like to control the frequency of the AC current.
Start with rectifying the source AC. And use it as the power source.How to increase or decrease the frequency of AC current linearly? Suggest me some ideas
