Abstract

Se describe un método para compensar voltajes en un grupo de capacitores de un dispositivo electrónico de potencia, tal como un inversor de potencia de niveles múltiples, que incluye hacer una determinación de compensación considerando si (i) inyectar energía en uno de los capacitores seleccionados de un elemento de almacenamiento de energía, o (ii) extraer energía de uno de los capacitores seleccionados en el elemento de almacenamiento de energía basándose en el voltaje de uno de los capacitores seleccionados, y ya sea inyectar energía en uno de los capacitores seleccionados del elemento de almacenamiento de energía, o extraer energía de uno de los capacitores seleccionados en el elemento de almacenamiento de energía basándose en la determinación de compensación. También, un circuito compensador de voltaje que implementa el método. En una implementación particular, se utiliza un segundo algoritmo derivativo. En otra implementación particular, se utiliza una comparación con un voltaje de capacitor promedio.
