Three-level, three-phase SiC AC/DC converter reference design

This reference design outlines how to implement a three-stage, three-phase SiC-based AC/DC converter with bidirectional functionality. The high switching frequency of 50kHz reduces the size of the magnetic components in the filter design and therefore increases the power density. SiC MOSFETs with switching losses enable higher DC bus voltages up to 800V and lower switching losses, with peak efficiencies greater than 97%. This design can be configured as a two-stage or three-stage rectifier. For design information on DC/AC implementation, see TIDA-01606 . The system is controlled by a single C2000 microcontroller (MCU), TMS320F28379D, which generates PWM waveforms for all power electronic switching devices in all operating modes.

This proven reference design outlines how to implement a three-level, three-phase DC/AC T-inverter stage based on SiC. The higher switching frequency of 50KHz reduces the size of the magnetic components of the filter design and therefore increases the power density.

Battery tester reference design for high current applications

Li-Ion battery formation and electrical testing require accurate voltage and current control, usually to better than ±0.05% over the specified temperature range.  This reference design proposes a solution for high-current (up to 50 A) battery tester applications supporting input (bus) voltages from 8 V–16 V and output load (battery) voltages from 0V–5V. The design utilizes an integrated multi-phase bidirectional controller, LM5170, combined with a high precisiondata converters and instrumentation amplifiers to achieve charge and discharge accuracies of 0.01% full scale. To maximize battery capacity and minimize battery formation time, the design uses highly-accurate constant current (CC) and constant voltage (CV) calibration loops with a simplified interface. All key design theories are described guiding users through the part selection process and optimization. Finally, schematic, board layout, hardware testing, and results are also presented.
