This article analyzes the implementation of control algorithm for a single-phase power inverter using digital signal controller (DSC). For this purpose, a floating-point digital signal controller with a trigonometric math unit was used. The controller’s task was to control the H-bridge through a dedicated driver for power MOSFET transistors. For this task, transistors made in NexFET technology with low channel resistance were used. The H-bridge is the main power device of a single-phase, two-level power inverter powered by a 12V battery. As a modulation method, regular modulation with carrier signal using a triangular signal was used. The main aim was to show the digital signal controller’s performance in real-time control of power inverters and to present the maximum sampling frequency of the inverter that can be obtained for the example having been analyzed.
