METHOD FOR CONTROL OF ELECTRIC POWER CONVERTER Russian patent published in 2000 - IPC

FIELD: power supply units. SUBSTANCE: method involves generation of control signal using sweep signal, which is produced from estimated interval from commutation of regulation unit to end of synchronization of increment of differentiated output signal, which is displaced by sum of mean values for synchronization interval of increment of differentiated output signal in interval before and after commutation of regulation unit. In vicinity of steady-state mode, sweep signal is set to same amplitude and opposite sign to real differentiated device output signal in moment, when regulation unit is switched. This results in commutation of regulation unit out of static error. In addition, moment of commutation of regulation unit takes into account voltage application of input and output lines of LC-circuit to derivative of output signal following after commutation of regulation unit. This results in stability of steady-state mode for wide range of parameters, so that control method may be used not only in pulse direct current converters, but also in controlled rectifiers of alternating current both with zero diode and without it. EFFECT: increased functional capabilities, elimination of static error, increased stability and improved quality of regulation. 2 dwg
