Abstract: A power converter controlled by a micro-controller unit (MCU) is effectively synchronized by using a signal received by a hardware subsystem of the MCU. The synchronization signal can control multiple power converters and can be generated by one power converter or a synchronization controller with generation of the synchronization signal generated using a hardware subsystem of an MCU, namely a hardware timer. The timer can be used to obtain a switch state from a memory table using direct memory access (DMA).
