Abstract

Un método permite la medición de una pérdida de inversor dentro de un circuito de control de motor para un aparato. El método incluye aplicar una corriente constante DC generada a partir de una primera tensión de alimentación AC a un arrollamiento de motor a través de un inversor en un primer ciclo de trabajo, medir una primera tensión que corresponda con la corriente a través del motor en un resistor de detección de corriente de motor, calcular una primera relación de la primera tensión medida en el resistor de detección de corriente de motor con una primera tensión de entrada DC que corresponda con la primera tensión de alimentación AC, identificar un segundo ciclo de trabajo a partir de la primera relación calculada, comparar el segundo ciclo de trabajo con el primer ciclo de trabajo e identificar un primer factor de pérdida de inversor a partir de la diferencia entre el primer ciclo de trabajo y el segundo ciclo de trabajo.
