The design helps management Vienna rectifiers in high-power methods. It consists of instruments for management, monitoring, and sooner improvement.
The Vienna rectifier energy topology is usually utilized in high-power, three-phase energy issue correction purposes, together with home equipment, electrical automobile (EV) chargers, and telecom rectifiers. Designing management for the rectifier may be advanced. TIDA-010257, a reference design from Texas Devices (TI) demonstrates a technique to regulate the ability stage utilizing the C2000 microcontroller (MCU). It additionally gives a graphical person interface (GUI) for monitoring and controlling the Vienna rectifier. The out there {hardware} and software program streamline the design course of, serving to cut back time to market. The design is appropriate for numerous high-power purposes, together with air conditioner out of doors models, warmth pumps, EV charging infrastructure, telecom rectifiers, and manufacturing unit automation and management methods.
Three-phase energy is extensively utilized in industrial purposes the place gear operates at excessive energy ranges. Many of those purposes, reminiscent of industrial air conditioners and EV chargers, use DC hundreds. To enhance energy high quality on the grid and cut back harmonic currents drawn by these hundreds, energy issue correction is required.
Among the many numerous energetic three-phase energy issue correction topologies, the Vienna rectifier is a well-liked selection. It operates in steady conduction mode (CCM), makes use of three-level switching, and locations much less voltage stress on energy units. Historically, Vienna rectifiers have used hysteresis-based management, however latest developments have proven that sine-triangle PWM can be a viable methodology. Nevertheless, designing this management may be difficult.
The TMS320F280013x is a part of the C2000 real-time microcontroller household, designed for prime effectivity in energy electronics purposes with ultra-low latency. It consists of as much as 256KB of flash reminiscence and as much as 36KB of on-chip SRAM for added storage. It additionally integrates high-performance analog parts which can be tightly coupled with the processing and PWM models, enabling quick and correct sign processing for management duties.
Right here’s a rewritten model of the part as a cleaner and extra concise rationalization, divided into distinct elements for readability:
The UCC53x0 collection consists of single-channel remoted gate drivers designed for driving MOSFETs, IGBTs, SiC MOSFETs, and GaN FETs. It’s well-suited for motor drives and industrial energy provides. In comparison with optocouplers, they provide decrease skew, sooner response, greater temperature operation, and improved CMTI. The AMC1350 is a high-accuracy remoted amplifier designed to separate low-voltage circuits from high-voltage environments. It’s appropriate for voltage sensing in DC/DC converters, frequency inverters, and motor or servo-drive purposes.
The TMCS1123 is a high-accuracy, galvanically remoted Corridor-effect present sensor that delivers a linear output voltage proportional to the enter present. With precision sign conditioning and built-in drift compensation, it achieves lower than 1.4% max sensitivity error over temperature and lifelong with out calibration, or beneath 1% with a one-time calibration.
