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.One method allows the measurement of an inverter loss within a motor control circuit for an apparatus. The method includes applying a constant DC current generated from a first AC supply voltage to a motor winding through an inverter in a first duty cycle, measuring a first voltage that corresponds to the current through the motor in a motor current detection resistor, calculate a first ratio of the first voltage measured in the motor current detection resistor with a first DC input voltage corresponding to the first AC supply voltage, identify a second duty cycle a From the first calculated relationship, compare the second work cycle with the first work cycle and identify a first inverter loss factor from the difference between the first work cycle and the second work cycle.
