  • Patent number: 10797611
    Abstract: A system and method for performing diagnostics in a medium voltage drive. The system includes a power cell and a bypass mechanism. The bypass mechanism is operably connected to output terminals of the power cell and configured to create a shunt path between the output terminals. The bypass mechanism includes a communication interface configured to transmit a bypass signal to a communication interface associated with the power cell in response to a state change. The method of performing diagnostics includes a controller transmitting an input voltage to a bypass mechanism of the power supply, thereby causing a state change of the bypass mechanism. The controller receives a signal from the power cell, wherein the signal indicates the power cell has detected the state change of the bypass mechanism. The controller then determines if the power cell is correctly associated with the bypass mechanism.
