Olá. Creio que achei um problema parecido com o seu. O divisor de clock do MCPWM é dividido em 10 vezes menor. Percebi isso quando o software da espressif-idf me indicou usar "mcpwm_prelude" ao invés da "driver/mcpwm". Então fiz os ajustes necessários e consegui 4000 ao invés de 400

Obrigado pela informação. Isso também se aplica ao Arduino IDE, não consigo encontrar o arquivo "mcpwm_prelude". Você pode me dizer onde o divisor está localizado, considerando que no meu código eu configurei o prescaller para um valor de 1.

@@yopiediy boa sorte. tente pesquisar as funções "mcpwm_group_set_resolution(mcpwm_unit_t mcpwm_num, unsigned long int resolution);" e "mcpwm_timer_set_resolution(mcpwm_unit_t mcpwm_num, mcpwm_timer_t timer_num, unsigned long int resolution);". estava olhando elas há pouco e parece que podem resolver nossos problemas. se ambas tiverem a mesma resolução (a documentação diz que a primeira função tem por padrão 10.000 de resolução e a segunda função possui uma resolução padrão de 1.000), pode funcionar. Outra coisa, o cálculo de suas senóides não parece muito otimizado... eu precisei calcular apenas um seno e depois a partir de identidades trigonométricas cheguei nos valores das outras fases sem cálculos árduos para o ESP32 .

Hello sir, sorry, I sent you a message a few days ago but apparently it never loaded, so I'm sending the same message. Is that I saw that in your KZread channel you developed a three phase inverter, using very good materials as they are ESP32 transformers and the output waves look good fidelity. My question is if it is possible to make a three-phase inverter by adding two current sensors and two voltage sensors to achieve a simple current control can be with a PI control, so that when different loads are connected to the consumption is leveled.
