Isolated measurement system with cooperatively-timed isolated power generation

A method of controlling an isolated measurement system, comprising:

• delivering power via a first isolator from the first side of an isolation barrier to a second side of an isolation barrier by an isolator driving signal,
• generating, on a first side of the isolation barrier, a clock signal defining timing of a predetermined operation of a measurement system on a second side of the isolation barrier,
• transmitting the clock signal to the second side via a second isolator, and
• disabling the isolator driving signal synchronously with the predetermined operation.

A system for an isolated measurement system comprising:

• a power transmitter provided on a first side of an isolation barrier,
• a power receiver provided on a second side of the isolation barrier,
• a measurement signal provided on the second side of the isolation barrier,
• a first isolator coupling the power transmitter to the power receiver,
• a second isolator to carry power measurement signals from the second side to the first side, and
• a power controller to modulate a control signal to the power transmitter, the control signal defining a duty cycle of activation of the power transmitter, wherein the control signal deactivates the power transmitter at times when the measurement system performs high precision operations.

A system for an isolated measurement system comprising:

• a power transmitter provided on a first side of an isolation barrier, having an output coupled to a first isolator,
• a control system provided in the first side having
• a first output, coupled to a second isolator, for a clock signal defining timing of a predetermined operation of a measurement system on a second side of the isolation barrier and
• a second output, coupled to the power transmitter, for a disabling signal that disables the power transmitter controller synchronously with the timing of the predetermined operation.
