Abstract:
A power converter interfaces a variable voltage and variable frequency motor to a fixed voltage and fixed frequency network. A first inverter is connected to the motor stator. A dc link is connected between the first inverter and a second inverter. Each inverter includes switches. A filter is connected between the second inverter and the network. A first controller for the first inverter uses a dc link voltage demand signal indicative of a desired dc link voltage to control the first inverter switches to achieve a desired dc link voltage level. A second controller for the second inverter uses a power demand signal indicative of a power to be transferred to the dc link from the network through the second inverter, and a voltage demand signal indicative of a voltage to be achieved at the filter to control the second inverter switches to achieve desired power and voltage levels.
