Abstract
The present disclosure relates to a method to allocate electrical power among tools in a bottomhole assembly disposed in a wellbore. A bottomhole assembly having an electric generator, an electrical bus, a bus master, and two or more tools is provided. One or more of the two or more tools has selectable power modes. Electrical power, up to a maximum output value, is provided through the electrical bus to the two or more tools using the electric generator. Electronic components of the two or more tools are synchronized, using the bus master to select a normal power mode or a low power mode for each tool having selectable power modes. The combined power requirements of the two or more tools at any given time do not exceed the maximum output value.
