The paper presents an approach to the software implementation of pulse-density modulation (PDM) control for H-bridge series-resonant converters. The formation of pulse-density modulated control signals directly by a microcontroller makes it possible to avoid using many additional chips for the hardware implementation of PDM control. For this purpose, four control patterns and transactions between them are described. Moreover, the features of the organization PDM sequences in the source code of the microcontroller are discussed, and an algorithm for choosing control patterns and preparing timer registers is shown.

W artykule przedstawiono podejście do implementacji programowej sterowania modulacją gęstości impulsów (PDM) dla przekształtników szeregowo-rezonansowych z mostkiem H. Tworzenie sygnałów sterujących o modulowanej gęstości impulsów bezpośrednio przez mikrokontroler umożliwia uniknięcie stosowania wielu dodatkowych układów scalonych do sprzętowej implementacji sterowania PDM. W tym celu opisano cztery wzorce sterowania oraz transakcje między nimi. Ponadto omówiono cechy organizacji sekwencji PDM w kodzie źródłowym mikrokontrolera oraz przedstawiono algorytm wyboru wzorców sterowania i przygotowania rejestrów czasowych.
