Abstract
Systems and methods are disclosed for managing a communication and control of power components. The system includes a parallel bus and plural peripheral devices. Each peripheral device is connected to the parallel bus. The system also includes a control module that is connected to the parallel bus, the control module including memory that stores control data and telemetry data associated with each peripheral device, and an interface that controls access to addressable locations in memory over the parallel bus.
Claims31
A digital control system for managing operation of a power system, comprising:
- a parallel bus;
- plural peripheral devices, wherein each peripheral device is connected to the parallel bus;
- a control module connected to the plural peripheral devices via the parallel bus, the control module having addressable memory to provide each peripheral device access to associated control information stored in the control module, each peripheral device being configured to access a unique location in the addressable memory and the control module, and the control module being configured to arbitrate access to the parallel bus among the plural peripheral devices;
- and
- a system controller configured to access the addressable memory locations of the control module to configure and monitor the plural peripheral devices,
- wherein at least one of the peripheral devices is a power converter peripheral that is configured to set operating conditions and voltage limits based on the control information, and store a status of the operating conditions and voltage limits at the unique location in the addressable memory of the control module for access by the system controller.
3 more elements
An integrated circuit that manages plural peripheral devices in a power system, comprising:
- an addressable memory device that stores control and telemetry data for each of the peripheral devices in the power system;
- a first bus interface that controls access to an addressable location in the memory device by the plural peripheral devices over a parallel bus;
- a second bus interface that controls access to the addressable location in the memory device by external processors for configuring and monitoring the plural peripheral devices over a control bus;
- and
- a controller configured to arbitrate access to the parallel bus among the plural peripheral devices for setting operating conditions and limits to regulate voltage supplied to a load, and configured to arbitrate access to the control bus among the external processors for monitoring a fault condition at the load when voltage parameters are outside predetermined limits.
2 more elements
A method of managing plural power converter peripherals in a power system, having a control module and a parallel bus comprising:
- accessing control data stored in an addressable memory location of the control module over the parallel bus, the addressable memory location being associated with a respective peripheral;
- setting operating conditions and limits at the respective power converter peripheral;
- executing power control and checking limits at respective power converter peripheral;
- determining whether the respective power converter peripheral is operating within predetermined limits;
- receiving, in the addressable memory location at the control module, status data of the respective power converter peripheral over the parallel bus, based on a result of the determining;
- accessing the status data of the respective power converter peripheral from the addressable memory location at the control module over a control bus;
- receiving, in another addressable memory location of the control module over the control bus, configuration data for the respective power converter peripheral;
- adjusting an operating condition of the respective power converter peripheral, based on the configuration data, when the respective power converter peripheral accesses the configuration data in the other addressable memory location.
5 more elements
A method of managing plural peripheral devices in a power system that includes a control module, a parallel bus, and a second bus, the method comprising:
- managing, at a control module, access among plural peripheral devices to addressable memory over a parallel bus so that each peripheral device stores status and telemetry data at a first location in the addressable memory and reads control data from a second location in the addressable memory for setting operating conditions and limits to regulate voltage supplied to a load;
- and
- controlling, at the control module, access by a system controller to the first location of the addressable memory over the second bus, wherein the system controller reads the status and telemetry data of an associated peripheral device and writes control data to the second location in addressable memory over the second bus for monitoring a fault condition at the load when voltage parameters are outside predetermined limits.
A control module that manages plural peripheral devices in a power system comprising:
- addressable memory;
- a first bus interface connected between the addressable memory and a parallel bus of the power system, wherein the first bus interface controls access to a unique location in the addressable memory by at least one of the plural peripheral devices over the parallel bus for setting operating conditions and limits to regulate voltage supplied to a load;
- a second bus interface that controls access to the unique location in the addressable memory by external processors for configuring and monitoring a fault condition at the at least one peripheral device over a second bus when voltage parameters are outside predetermined limits;
- and
- a voltage regulator control circuit that controls power distributed to the at least one peripheral device.
