Abstract

Un sistema incluye un accionador de frecuencia variable (VFD) que comprende un inversor que tiene una salida configurada para acoplarse a un motor y un interruptor configurado para acoplar una fuente de potencia al motor para eludir el VFD. El sistema incluye además un circuito de control configurado para sincronizar el VFD con la fuente de alimentación, para operar el interruptor para acoplar la fuente de alimentación y el VFD en paralelo y para desactivar posteriormente el inversor en respuesta a una corriente del inversor. En algunas modalidades, una frecuencia de PWM del VFD puede aumentar temporalmente cuando se transfiere el motor de la fuente de alimentación al VFD.
