Texas Instruments UCC21530 | Demoboard TIDA-010210
6.6-kW three-phase, three-level ANPC inverter/PFC bidirectional power stage reference design
Overview
| Topology | Power Factor Correction |
| Input voltage | 600-1000 V |
| Switching frequency | 50-60 kHz |
| Output 1 | 400 V / 10 A |
Description
This reference design provides a design template for implementing a three-level, three-phase, silicon carbide/gallium nitride (SiC/GaN) based ANPC inverter power stage. The use of fast-switching power devices makes it possible to switch at a higher frequency of 100 kHz, reducing the size of magnetics for the filter and increasing the power density of the power stage. The multilevel topology allows the use of 600-V rated power devices at higher DC bus voltages of up to 1000 V. The lower switching voltage stress reduces switching losses resulting in a peak efficiency of 98.5%. This design is modular in construction, making it configurable to work with SiC or GaN power devices with the same filter stage.
Features
- Power stage for three phase inverters/PFCs usingSiC/GaN switch
- 650-V rated switches in 800-V system (due tothree levels)
- Novel on-board protection implemented using CLBof C2000
- Iso-dual channel driver supports high frequencyoperation (100KHz)
- Shunt based current sense (high accuracy andlinearity over temperature)
Typical applications
- Solar String Inverters, Solar Central Inverters
- Energy storage power conversion system (PCS)
