TI TIDA－0145三相变频马达驱动参考设计
TI公司的TIDA-0145是紧凑的非隔离三相逆变器参考设计,设计由C2000™ MCU控制,栅极驱动器UCC5320S.驱动电压200到480-V AC,连续电流10Arms,用于变频AC逆变器驱动和伺服驱动.本文介绍了通用马达控制框图,参考设计TIDA-0145主要特性和系统指标,框图,电路图,材料清单和PCB设计图.
This reference design realizes a three-phase invertersubsystem for variable frequency AC inverter drivesand servo drives. This design is particularly suited fordrive architectures in which the microcontroller groundand the inverter ground are non-isolated. Basicisolated gate driver UCC5320S is used for driving thehigh-side inverter switches, and the small and compactsix-pin UCC27531 low-side gate driver is used fordriving the bottom switches. The reinforced isolation ismoved to the UART communication channel.Currentsensing in the inverter half-bridge leg is done in twophases using shunt resistors and the dual operationalamplifier TLV9062. This drive architecture results inreduced number of reinforced isolated channels andenables a cost optimized compact solution. The designis controlled by a C2000™ microcontroller.
