METHOD OF EVEN CURRENT DISTRIBUTION CONTROL IN MULTI-CHANEL PULSE VOLTAGE TRANSDUCER

摘要

FIELD: electricity. ^ SUBSTANCE: stated invention is related to electric engineering and may be used in sources of power supply and electric drives, which are characterised with wide range of load current change. In control method determination of pulse component of throttle current of output filter of every channel is carried out as difference of measured values of output filter throttle current and load current divided into number of operating channels, mismatch between output current of this channel and average load current value per channel is automatically accounted. Supply of synchronising pulses to parallel operating channels with shift equal to duration of synchronisation period divided into number of channels evenly shifts switching of key elements of these channels, thus providing multi-phase control. ^ EFFECT: expansion of functional resources due to multi-phase control and leveling of output currents of parallel operating transformation channels at multi-channel version of voltage transducer. ^ 1 dwg
