MODULAR INVERTER BAY AND CONTROL METHOD FOR SAME FOR A SET OF ELECTRIC MACHINES WITH NO POSITION SENSORS

摘要

A modular power bay for an aircraft comprises a plurality of electric machines, a plurality of inverters, and a control member configured to assign to at least one machine one or more inverters, according to the operational requirements of the plurality of machines. The control member comprises: an observer, able to measure phase currents and phase-neutral voltages of an electrical power supply signal of the machine, an estimator, able to determine a rotor position, based on the measurements of at least one observer, means for communicating, to each of the inverters: a control instruction for each of the inverters for responding to the operational requirement of said machine, measurements of at least one observer, or of the estimated rotor position.

1. A modular power bay for an aircraft comprising a plurality of electric machines, a plurality of inverters, and a control member configured to assign to at least one machine one or more inverters, according to the operational requirements of each machine of the plurality of machines,
wherein the control member comprises, for the at least one machine:
at least one observer, able to measure phase currents and phase-neutral voltages of an electrical power supply signal of said machine,at least one estimator, able to determine a rotor position of said machine, based on the measurements of at least one observer,means for communicating, to the inverter/each of the inverters assigned to said machine, the following data:
a control instruction for the inverter/each of the inverters to respond to the operational requirement of said machine,measurements of at least one observer, or of the estimated rotor position; the inverter/each of the inverters being configured to generate an electrical power supply signal for said machine according to the data transmitted.
