1, 10KW three-phase 3-level grid-network inverter reference design for solar string inverter
This verified reference design outlines how to achieve SiC-based three-level three-phase DC / AC grid-based. 50kHz's higher switching frequency reduces the magnetic component size of the filter design and thus increases the power density. By using SiC MOSFETs that reduce switch loss, higher DC bus voltages and lower switching losses are ensured, and 99% peak efficiency can be achieved. This design can be configured as a two or three-stage inverter.

2, based on STM32 sine wave inverter design
I am interested in the inverter, after reference to various information, after two revices, this pure sinusoidal inverter has been made. Design power at 300W. Sine wave from DC to SPWM, which uses STM32C8T6 (STM32C8T6 Data Manual) as a master chip, and provides high pressure, low pressure, over-power, and short-circuit protection. Now open source. I hope to communicate with friends who like to do inverter and improve.
The SPWM regulation is temporarily used in a 310 / DC to make a modulation ratio. From debugging to now 5 STM32 is a CPU short circuit, the reason is why there is a daily check.
This machine carries a hand drill, a soymilk, a TV, and a desktop computer. The soymilk is no problem, and the protection will be triggered after a few seconds. After the desktop computer worked for 10 minutes, the battery was no electricity, and he didn't try again.

Share a sine wave inverter design project based on STM32 single-chip microcomputer.
summary:
As you know, the city's electricity or other alternating current can be expanded to DC electrical supply by a one-way conductive rectification of diode or thyristor. This process of converting AC changes into direct current, we are called rectification, and it is also called a change. So? We naturally think that it should be the process of converting DC electrically converted to flow. The inverter power is to turn the DC electrically converted to transition to the flow of direct flow with respect to the rectifier. The inverter power is also called an inverter, and the main unit circuit of the inverter is tested in the attachment. Be
