REDUNDANT-ARCHITECTURE DC VOLTAGE CONVERTER Russian patent published in 2008 - IPC H02J9/06 H02J7/34 H02H7/10 

FIELD: electrical engineering; no-break power supply to responsible industrial and military transient-load consumers.

SUBSTANCE: proposed parallel redundant-architecture DC converter characterized in enhanced stability to switching pulse noise has (N + 1) similar DC/DC modules. Each DC/DC module incorporates microcontroller control system. DC/DC module control systems incorporate provision for data exchange over bus, type CAN-bus, and equally perform their functions, that is, they are not separated according to "Drive control system" and "Driven control system" criteria. Unique identical algorithms implemented in all microcontroller systems of DC/DC modules equally performing their functions provide for transfer of one of these modules (at rated load) to stand-by mode, uniform distribution of transient load among parallel-running DC/DC modules, automatic throw of stand-by DC/DC module in operation in case load rises above rated value or one of DC/DC modules fails, and informant peripheral control systems about occurrence of failure in converter and, hence, about its operation without stand-by power support. Failure message received by peripheral control system enables attending personnel to adequately respond to situation by recovering trouble-free operation of converter under redundant-power condition.

EFFECT: enlarged functional capabilities, uniform load distribution among parallel-running converter channels, enhanced load-carrying capacity and failure tolerance.
