Abstract
According to some embodiments, a battery cluster controller includes a serial interface configured to receive waveform data and a rank over a serial communication bus, a processor configured to generate a switching parameter based on the rank and the waveform data, and a modulation unit configured with the switching parameter to generate a bridge configuration signal to control a bridge for selectively connecting a battery element to an output terminal to generate a first component of a waveform.

1-20. (canceled)
A method, comprising:
- connecting a cluster controller of a battery cluster to a serial communication bus;
- receiving waveform data and a rank in the cluster controller from the serial communication bus;
- receiving a waveform start signal in the cluster controller from the serial communication bus;
- and
- responsive to receiving the waveform start signal, controlling, in the cluster controller, a bridge of the battery cluster to connect a battery terminal of the battery cluster to an output terminal based on the waveform data and the rank to generate a component of a waveform.
A battery cluster controller, comprising:
- a communication interface configured to receive waveform data and a rank;
- a processor configured to generate a switching parameter based on the rank and the waveform data;
- a modulation unit configured with the switching parameter to generate a bridge configuration signal for selectively connecting a battery element to an output terminal via a bridge for generation of a component of a waveform;
- a clock unit connected to the modulation unit and configured to generate a clock signal based on a trim parameter;
- and
- a counter connected to the clock unit,
- wherein the processor is configured to:
- receive a synchronization message, wherein the synchronization message comprises a start message and a stop message and
- adjust the trim parameter based on the synchronization message,
- start the counter responsive to receiving the start message,
- stop the counter responsive to receiving the stop message to generate a measured count,
- determine a frequency error based on the measured count and an ideal count for the synchronization message, and
- adjust the trim parameter based on the frequency error.
A system, comprising:
- an output terminal;
- a serial communication bus;
- a battery cluster comprising:
- a battery element;
- a bridge configured to selectively connect the battery element to the output terminal based on a state of the bridge;
- and
- a cluster controller connected to the bridge and the serial communication bus and configured to:
- receive waveform data and a rank from the serial communication bus;
- receive a waveform start signal from the serial communication bus;
- and
- control the bridge to connect the battery element to the output terminal based on the waveform data and the rank to generate a component of a waveform.
