Данный проект представляет собой безмостовой преобразователь с коррекцией коэффициента мощности (PFC) на 300 Вт с цифровым управлением. Отличительной особенностью любого безмостового преобразователя с коррекцией коэффициента мощности является то, что отсутствует необходимость в использовании диодного моста на его входе. Благодаря этому уменьшаются потери мощности, которые обычно имеют место быть в диодном мосте, и в конечном счёте повышается суммарный КПД системы. В данном проекте цифровым контроллером преобразователя с коррекцией коэффициента мощности является микроконтроллер (MCU) TMS320F28035 семейства C2000™ Piccolo™, управляющий двумя повышающими силовыми каскадами, которые и образуют безмостовой преобразователь с PFC. Поочерёдно задействуя данные каскады во время циклов положительного и отрицательного переменного напряжения электросети, микроконтроллер Piccolo выполняет как выпрямление переменного тока в постоянный, так и управление коэффициентом мощности.

This design is a digitally controlled 300W resonant LLC half-bridge DC/DC converter with added synchronous rectification. The resonant LLC power topology is valued for its inherently high levels of efficiency credited to high frequency, low loss resonant switching. However, implementation of such a power converter can be challenging since the control theory is based in frequency modulation of the converter rather than the more typically seen duty cycle modulation. This design guides users step-by-step through the complexities of a resonant LLC half-bridge converter, melding software and hardware design approaches to implement a complete high performance converter. The C2000™ Piccolo™ microcontroller is the digital controller for this design, enabling the resonant converter to operate at greater than 90% efficiency across wide load ranges, and with peak efficiency greater than 93%.
