Continuous-Conduction-Mode (CCM) Totem-pole power factor correction (PFC) is a simple but efficient power converter. To achieve 99% efficiency, there are many design details that need to be taken into account. The PMP20873 reference design uses TI’s 600VGaN power stage, LMG3410, and TI’s UCD3138 digital controller. The design overview provides more details on the CCM Totem-Pole topology operation, gives the detail design considerations of the circuit, and provides magnetics and firmware control design considerations. This converter design operates at 100KHz. A soft start at AC line crossover minimizes current spike and lowers THD. The PFC Firmware measures AC current and PFC output voltage in real-time and predicts the dead time needed for the switch node to complete a full swing. The adaptive dead time control effectively minimizes both switching loss and GaN FET body diode conduction loss. A GUI is available to support parameter setting and control loop tuning.
The style of enameled wire is as usual, and the craftsmanship is still excellent. The power board designed this time is made of double panels, and a copper-laying design is applied. The insulation layer is laid first and then the copper. If the device on the front needs to be grounded, break the insulation layer and solder it to the copper.
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. By using SiC MOSFETs that reduce switching losses, higher DC bus voltages up to 1000V and lower switching losses are ensured, resulting in peak efficiencies of 99%. This design can be configured as a two- or three-level inverter. 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.
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.
