Abstract
The present disclosure provides a method for controlling a surgical instrument. The method includes connecting a power assembly to a control circuit, wherein the power assembly is configured to provide a source voltage, energizing, by the power assembly, a voltage boost convertor circuit configured to provide a set voltage greater than the source voltage, and energizing, by the voltage boost convertor, one or more voltage convertors configured to provide one or more operating voltages to one or more circuit components.

21. A powered surgical instrument, comprising:
-
a housing comprising a motor; a shaft extending from said housing; an end effector extending from said shaft, wherein said end effector is configured to perform at least one end effector function; a power source; a processor; a motor controller configured to control said motor; a control circuit, comprising; a first segment configured to supply said processor with a first voltage from said power source; and a second segment configured to supply said motor controller with a second voltage from said power source, wherein said second voltage is different than said first voltage; a current sensing segment configured to measure current draw of said motor controller; and a control circuit safety system configured to provide an additional voltage to said first segment when said second segment experiences a voltage drop due to high current demand from said motor.
