System and Method for Electrosurgical Generator Power Measurement

A system for measuring electrosurgical generator output, comprising:

• an active load section, comprising:
• an input adapted to receive electrosurgical energy from an electrosurgical generator under test;
• a voltage sensor in communication with the input and configured to output a voltage sensor signal;
• a current sensor in communication with the input and configured to output a current sensor signal;
• an active load operably coupled to the input and configured to present a variable load to the electrosurgical generator under test in response to an active load drive signal;
• and
• a signal conditioning driver in communication with the active load and configured to convert an active load control signal into an active load drive signal;
• and
• a control section, comprising:
• an input-output processor;
• a voltage sensor input in communication with the input-output processor and configured to receive the voltage sensor signal;
• a current sensor input in communication with the input-output processor and configured to receive the current sensor signal;
• a proportional-integral-derivative control module in communication with the input-output processor and configured to output the active load control signal;
• a lookup table in communication with the proportional-integral-derivative control module and configured to store a test profile;
• and
• a control processor configured to output a generator control signal in communication with the input-output processor, the proportional-integral-derivative control module, and the lookup table.
