[5, 3, 5, 3, ...] = [4, 4, 4, 4, ...] + [1, -1, 1, -1, ...]
Every current that varies with a regular frequency is just the sum of a DC current and an AC current that reverses flow. I guess in most applications one can decompose them and analyze the two components separately.
- dredmorbius 10y agoSure, you can decompose them. But if you're outputting DC, again, you never have to worry about subtracting from an existing DC line voltage. If you're outputting AC, you have to worry about wave interference.
- euyyn 10y agoI was just talking about your distinction between a current that reverses flow, and one that varies without reversing flow.
