Abstract
Способ управления импульсным резервированным стабилизатором тока, основанный на широтно-импульсной модуляции сигнала управления инвертором, заключающийся в том, что измерение текущего значения стабилизируемого тока производят непосредственно в цепи нагрузки, оцифровывают и сохраняют в памяти микроконтроллера, вычисляют программным способом скважность ШИМ-сигнала одновременно по последовательности сохраненных значений и заданному значению тока и только после этого формируют ШИМ-сигнал управления инвертором, а затем выпрямляют и сглаживают выходной ток, отличающийся тем, что управление импульсным резервированным стабилизатором тока производится по двум идентичным каналам, соединенным между собой линией связи по интерфейсу RS-485 и подключенным одновременно на одну нагрузку, причем изначально управление стабилизатором тока ведется по основному каналу, а при возникновении в нем одной возможной неисправности управление стабилизатором тока передается резервному каналу.A method for controlling a pulsed redundant current stabilizer based on pulse-width modulation of the inverter control signal, which means that the current value of the stabilized current is measured directly in the load circuit, digitized and stored in the microcontroller, and the PWM signal duty cycle is calculated simultaneously using the sequence stored values and the set current value, and only after that form the PWM control signal of the inverter, and then rectify and ironing the output current, characterized in that the control of the pulsed redundant current stabilizer is performed through two identical channels, interconnected by a communication line via the RS-485 interface and connected simultaneously to the same load, and the current stabilizer is initially controlled through the main channel, and if In one possible malfunction, the control of the current stabilizer is transferred to the backup channel.
