ISOLATED MEASUREMENT SYSTEM WITH COOPERATIVELY-TIMED ISOLATED POWER GENERATION
First Claim
1. 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,an isolator coupling the power transmitter to the power receiver, anda control system, provided in the first side, to provide a clock signal defining timing of a predetermined operation of a measurement system in the second side and to generate a disabling signal to the power transmitter controller synchronously with the timing of the predetermined operation.

Abstract
A power delivery system is disclosed for an isolated measurement system in which a power transmitter and power receiver are provided at powered and unpowered sides of an isolation barrier, respectively. The power transmitter and power receiver may be coupled by an isolator. The power transmitter may deliver power to the power receiver to power components on the unpowered side of the isolation barrier. The system may include a controller provided in the powered side to generate a clock signal defining timing of a predetermined operation of the measurement system and to generate a disabling signal to the power transmitter controller synchronously with the timing of the predetermined operation.

15. 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. 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. - View Dependent Claims (27, 28, 29, 30)

31. 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.
