Проанализирована возможность использования микроконтроллера семейства STM32F1хх для управления двухзвенным преобразователем электрической энергии с разделенной коммутацией. Предложен способ использования таймеров микроконтроллера с целью аппаратной реализации временных последовательностей импульсов управления. Работоспособность предложенных решений подтверждена физическим моделированием.Purpose. The objective of this article is to analyze the possibilities and features of STM32 core microcontroller as a power converter control system with realizing the algorithm of soft switching. Methodology. At mathematical modelling are considered functional, and cost indexes of power converters that allows observing engineering and economic aspects of digital control system. For the purpose of raise of level of adequacy of models, losses of power are considered. Results. A method of forming a power converter control pulses based on its mathematical modeling was developed. Digital control system is realized on a microcontroller STM32. Experimental investigations of physical converter model confirmed the absence of hard switching of power switches. Given waveforms confirm ZVS and ZCS commutation and non-dissipative snubbers influence to commutation of power switches Originality. For the first time provides a method for the use of microcontroller hardware: timers and its synchronization for control of dual active bridge DC–DC converter with soft switching (split commutation). Practical value. The use of modern microcontrollers can greatly simplify the process of synthesis and adjustment of digital control systems; fully assume the function of generating control pulses on their hardware. The studies make it possible to expand the use of microcontrollers STM32F1xx F4xx in electric power converters control systems as a core element the formation the time intervals and power switch control pulse, and elements of control systems. The proposed approach can be used in the design of control systems in series/parallel-connected inverters with mutual synchronization sequences of control pulses.ruхарактеристики энергетическиепотери динамическиемикроконтроллеркоммутация мягкаяZCSZVSPWMтаймерсинхронизацияpower characteristicsdynamic lossesmicrocontrollersoft switchingtimersynchronizationArticle
