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.
