INVERTER CONTROL METHOD AND INVERTER CONTROL DEVICE

Provided are an inverter control method and an inverter control device. The inverter control device (31) receives input of an ON signal and an OFF signal from a controller (10) and determines an output command value for an inverter output (32) on the basis of the signals. If the OFF signal is input,...

Zusammenfassung:	Provided are an inverter control method and an inverter control device. The inverter control device (31) receives input of an ON signal and an OFF signal from a controller (10) and determines an output command value for an inverter output (32) on the basis of the signals. If the OFF signal is input, the output command value for the inverter output (32) is a prescribed minimum value, and if the ON signal is input, the output command value for the inverter output (32) is determined on the basis of a time interval associated with the ON signal and the OFF signal. Moreover, the inverter control device (31) sets the output command value for the inverter output (32) to the OFF value when current in a C-phase which is provided with an internal overload protector (41) is blocked and R-phase current flow is detected. L'invention concerne un procédé de commande d'onduleur et un dispositif de commande d'onduleur. Le dispositif de commande d'onduleur (31) reçoit un signal de marche et un signal d'arrêt provenant d'un dispositif de commande (10) et détermine une valeur de commande de sortie pour une sortie de l'onduleur (32) en fonction des signaux. Si le signal d'arrêt est reçu, la valeur de commande de la sortie de l'onduleur (32) est une valeur minimale prescrite, et si le signal de marche est reçu, la valeur de commande de la sortie de l'onduleur (32) est déterminée sur la base d'un intervalle de temps associé au signal de marche et au signal d'arrêt. En outre, le dispositif de commande d'onduleur (31) définit la valeur de commande de la sortie de l'onduleur (32) sur la valeur ARRÊT lorsque le courant d'une phase C pourvue d'un dispositif interne de protection contre les surcharges (41) est bloqué et qu'un flux de courant de phase R est détecté.
