Abstract: Control circuitry of a motor drive provides commands for operation of power circuitry based at least in part on signals exchanged with functional circuits, such as for system data and control data, such as feedback of motor or system parameters. The functional circuits may operate at different data rates, with different interrupt intervals, depending upon their capabilities. The control circuitry accommodates all of these flexibly. A physical backplane printed circuit board comprising independent data lines for each functional circuit allows for independent configuration of the data rates, interrupt intervals and communications between the control circuitry and the functional circuits.

Abstract: Control circuitry of a motor drive provides commands for operation of power circuitry in cooperation with peripheral circuits and devices, such as converters, inverters, feedback precharge circuits, feedback devices, interfaces, and so forth. The communications with the devices is handled by fiber optic communications circuitry that implements a flexible scheme of dynamic interval communication depending upon the capabilities and design of the peripheral circuit or device. The communication may be in accordance with a plurality of predetermined schemes, each having different data transfer rates, data allocations, and so forth. The schemes may each set communications protocols (e.g., timing) over a high speed interface between the fiber optic communications circuitry on one side and over fiber optic cables to the peripherals on another side.

Abstract: Techniques include systems and methods of synchronizing multiple parallel inverters in a power converter system. In one embodiment, control circuitry is connected to a power layer interface circuitry at each of the parallel inverters, via an optical fiber interface. The system is synchronized by transmitting a synchronizing pulse to each of the inverters. Depending on the operational mode of the system, different data exchanges may occur in response to the pulse. In an off mode, power up and power down data may be exchanged between the control circuitry and the inverters. In an initiating mode, identification data may be transmitted from the inverters to the control circuitry. In an active mode, control data may be sent from the control circuitry to the inverters. In some embodiments, the inverters also transmit feedback data and/or acknowledgement signals to the control circuitry. Power layer circuitry of the inverter adjusts a local clock based upon sampled data from the control circuitry to maintain synchronicity of the inverters between synchronization pulses.
