Applications are powered by an external source of electricity that can be a battery, a USB cable, or AC current for example. These sources can be noisy, especially if they supply power applications such as motors. Furthermore, the voltage can vary a lot, in the case of batteries depending on the. .
According to the principle of UPS, an AC sine wave online uninterruptible power supply based on STM32 is designed. The system adopts mains power, outputs corresponding DC power through isolation transformer, autotransformer and rectifier module, and then connects to single-phase full-bridge. .
In most non-battery applications, power is supplied to the microcontroller (MCU) using a step-down transformer, the output of which is rectified, filtered and regulated. However, in many smaller low-cost applications, the cost of the transformer becomes the key factor in the system. Under these. .
This article covers general aspects about designing power supplies for STM32 based applications. It provides general guidelines on important characteristics, how to choose components, and optional features related to power supplies. The first part is about power supplies in general. Define the main.
