Short Range Radar (SRR) Reference Design

The TIDEP-0092 reference design provides a foundation for short-range radar (SRR) applications using the AWR1642 evaluation module (EVM). This design allows the estimation and tracking of the position (in the azimuthal plane) and velocity of objects in its field of view up to 80 m,  travelling as fast as 90kmph.  The AWR1642 is configured to be a multi-mode radar, meaning that, while it tracks objects at 80m, it can also generate a rich point cloud of objects at 20m, so that both cars at a distance, and smaller obstacles close-by can be detected.

Interleaved CCM Totem Pole Bridgeless Power Factor Correction (PFC) Reference Design

Interleaved Continuous Conduction Mode (CCM) Totem Pole (TTPL) Bridgeless Power Factor Correction (PFC) using high-bandgap GaN devices is an attractive power topology due to its high power efficiency and reduced size. This design illustrates the use of a C2000™ MCU and LMG3410 GaN FET module to control this power stage. To improve efficiency, this design uses adaptive dead time and phase shedding methods. Nonlinear voltage compensators are designed to reduce overshoot and undershoot during transients. This design chooses a software phase locked loop (SPLL) based approach to accurately drive the totem pole bridge. The hardware and software used in this design help reduce your time to market.

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.
