2-phase phase angle control
2-phase phase angle control
(OP)
Hi All. I'm familiar with and have built plenty of single phase ramp & comparator type leading-edge phase angle controllers, but currently have an application that requires the voltage to be derived from two of the three phases (UK supply). My maths is not up to creating an excel graph to represent voltage throughout the cycle of two 120 degree separated signals and I'm really struggling to visualise what a 2-phase signal would look like graphically. I guess the question at the root of this is "what do I sync to?" or is even this question too simplistic? Thanks.

Please don't connect a scope directly to the line without an isolating probe - isolating probes are much cheaper than buying a new scope but more importantly they protect you from the high energy circuits: I've always considered being dead as damned inconvenient.

re. probes: I was thinking more on the lines of h
