摘要:半橋功率級是電力電子系統(tǒng)中的基本開關(guān)單元,應(yīng)用于電源轉(zhuǎn)換器、電機驅(qū)動器和D類功率放大器等電路設(shè)計中。本文介紹了一種系統(tǒng)方法,該方法利用預(yù)充電驅(qū)動電源方案和欠壓鎖定(UVLO)機制的控制策略,確保半橋電路中高邊和低邊開關(guān)的同步性。傳統(tǒng)的基于自舉電源的半橋驅(qū)動存在固有局限性,包括高邊和低邊驅(qū)動器之間電源的不對稱性,這會破壞開關(guān)的同步性和開關(guān)管的工作特性。本文通過詳細的電路設(shè)計和SPICE仿真驗證了該方法在改善開關(guān)同步性和可靠性方面的有效性,特別是對于GaN和SiC晶體管這種對驅(qū)動電壓范圍要求比較高的驅(qū)動更有應(yīng)用意義。

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.
