Abstract: front page image
(EN)When simultaneously driving two or more inverter circuits (9) among multiple inverter circuits (9), a control means (25) drives the applicable inverter circuits (9) using the same frequency, obtains currents output from the respective inverter circuits (9) driven, and controls the driving of the inverter circuits (9) so as to reduce the phase differences among the respective output currents obtained. A load determining means (26) determines a load on the basis of the output currents detected by output current detection means (28) of the driven inverter circuits (9) and input power or output power detected by a power detection means.
(FR)Lorsque l'on active deux ou plus de deux circuits onduleurs (9) parmi de multiples circuits onduleurs (9), un moyen de commande (25) active les circuits onduleurs applicables (9) en utilisant la même fréquence, obtient des courants de sortie des circuits onduleurs respectifs (9) activés et commande l'activation des circuits onduleurs (9) de manière à réduire les différences de phase parmi les courants de sortie respectifs obtenus. Un moyen de détermination de la charge (26) détermine une charge sur la base des courants de sortie détectés par des moyens de détection de courant de sortie (28) des circuits onduleurs (9) activés et des énergies d'entrée et de sortie détectées par un moyen de détection d'énergie.
