Abstract: The present invention provides a control apparatus for detecting at an early stage a short circuit between the terminals of an electrolytic capacitor, and detecting a short circuit between a load that is connected in parallel to the electrolytic capacitor, the apparatus performing appropriate processing before an adverse effect is inflicted on peripheral equipment. In the control apparatus (4), microcomputers (5, 6) switch on a second relay (84); an electrolytic capacitor (83) is gradually charged via a current-limiting resistor (85); a first voltage detection control for detecting a voltage between terminals of the electrolytic capacitor (83) is performed when a first set time period has elapsed after the second relay (84) has been switched on; and a second voltage detection control for detecting a voltage between the terminals of the electrolytic capacitor (83) is performed when a second set time period, which is longer than the first set time period, has elapsed after the second relay (84) has been switched on.

Abstract: Un entraînement à vitesse variable d'un moteur à induction auto-excité utilise un procédé connu d'auto-excitation où un condensateur est connecté en parallèle au moteur. L'alimentation est fournie par un convertisseur d'alimentation, une liaison à courant continu et un convertisseur en cascade, ce dernier fonctionnant à la fréquence du moteur. Le convertisseur en cascade comporte un circuit de commutation de dérivation du courant comprenant un banc de condensateurs connecté aux bornes du moteur et au neutre entre une paire de thyristors connectés sur la liaison à courant continu.

Abstract: A self-extinguishing element (14,) such as a gate turn-off thyristor (GTO) is used for each arm of the inverter (14). A capacitive load (16) is connected to the output terminal of the inverter.In a region where the output frequency of the inverter is low, the self-extinguishing element is forcibly commutated. In a high-frequency region, where the output frequency of the inverter is higher than that in the low-frequency region, the capacitive load causes the self-extinguishing element to be load-commutated.

Abstract: Power conversion systems and methods are provided for ride through of abnormal grid conditions or disturbances, in which a system rectifier is operated in a first mode to regulate a DC voltage of an intermediate DC circuit, an inverter is operated in the first mode to convert DC power from the intermediate DC circuit to provide AC output power to drive a load. In response to detecting an abnormal grid condition, the system changes to a second mode in which the rectifier is turned off and the inverter regulates the DC voltage of the intermediate DC circuit using power from the load.
