摘要:半桥功率级是电力电子系统中的基本开关单元,应用于电源转换器、电机驱动器和D类功率放大器等电路设计中。本文介绍了一种系统方法,该方法利用预充电驱动电源方案和欠压锁定(UVLO)机制的控制策略,确保半桥电路中高边和低边开关的同步性。传统的基于自举电源的半桥驱动存在固有局限性,包括高边和低边驱动器之间电源的不对称性,这会破坏开关的同步性和开关管的工作特性。本文通过详细的电路设计和SPICE仿真验证了该方法在改善开关同步性和可靠性方面的有效性,特别是对于GaN和SiC晶体管这种对驱动电压范围要求比较高的驱动更有应用意义。

The EVLSPIN32G4-ACT edge AI motor drive reference design simplifies the creation of smart actuators. This design is based on the STSPIN32G4, a 3-phase motor driver for advanced motor control systems. It is designed to work with ST's STWIN.box (STEVAL-STWINBX1), a wireless industrial sensor node, to fast-track the development of systems that merge precise motor control with real-time environmental data analysis and IoT connectivity.
The EVLDRIVE101-HPD (High Power Density) motor-drive reference design packs a 3-phase gate driver, STM32G0 microcontroller, and 750W power stage on a circular PCB just 50mm in diameter. The board features extremely low power consumption in sleep mode, below 1uA, and its tiny outline can fit directly in equipment like hairdryers, handheld vacuums, power tools, and fans. It also fits easily into drones, robots, and drives for industrial equipment such as pumps and process-automation systems.
ST’s STSPIN32 drivers combine a general-purpose STM32 microcontroller (MCU) with a feature-rich three-phase gate driver to simplify design, save PCB area and accelerate time to market. The eight new STSPIN32G0 devices contain gate drivers rated 45V, 250V and 600V, targeting applications from battery-operated appliances and power tools to industrial automation, robots, HVAC systems and line-powered home appliances.
The EVLSERVO1 servo driver reference design from STMicroelectronics offers a highly compact solution specifically engineered for high-power motor-control applications, providing designers with a turnkey platform to explore, develop, and prototype without compromises.
