CONTROL DEVICE FOR DIRECT-CURRENT PULSE CONVERTERS (VERSIONS) Russian patent published in 2012 - IPC G05F1/56 

FIELD: electricity.

SUBSTANCE: control device for one-phase pulse converter contains sawtooth voltage generator on the basis of integrator with threshold element and comparator. Between control voltage circuit and integrator input there is divider dividing control voltage to amplitude of sawtooth voltage and converter with converting function proportional to required dependency of voltage frequency on duty factor. Control device for multi-phase pulse converter contains sawtooth voltage generators based on integrators and comparators corresponding to number of pulse converter phases, at that inputs of all integrators are connected to output of converter with converting function proportional to required dependency of voltage frequency on duty factor and zero-setting input of each follow-up integrator is connected to output of comparator that generates control voltage for key element of previous converter phase.

EFFECT: enhancement of functional capabilities with receipt of required dependency of converter voltage frequency on duty factor at frequency-width regulation.
