Abstract:
(EN) A method for controlling an optically-coupled isolation vehicle-mounted power supply photovoltaic inverter. The inverter comprises a first to four switching circuits (S1, S2, S3, S4). Control ends of the switching circuits are connected to an optically-coupled isolation circuit. In a positive half-circle for outputting a current, the third switching circuit, the fourth switching circuit and a second free-wheeling circuit (S6, D6) are controlled to always maintain a turn-off state, a first free-wheeling circuit (S5, D5) is controlled to always maintain a turn-on state, and the optically-coupled isolation circuit is controlled to maintain a synchronous turn-on state with the first and second switching circuits; and in a negative half-circle for outputting a current, the first switching circuit, the second switching circuit, and the first free-wheeling circuit are controlled to always maintain the turn-off state, the second free-wheeling circuit is controlled to always maintain the turn-on state, and the optically-coupled isolation circuit is controlled to maintain a synchronous turn-on state with the third and forth switching circuits. The method reduces switching loss and conduction loss.
(FR) L'invention porte sur un procédé de commande d'un onduleur photovoltaïque d'alimentation, à bord d'un véhicule et à isolation par couplage optique. L'onduleur comprend des premier à quatrième circuits de commutation (S1, S2, S3, S4). Des bornes de commande des circuits de commutation sont connectées à un circuit d'isolation par couplage optique. Dans un demi-cercle de distribution de courant positif, le troisième circuit de commutation, le quatrième circuit de commutation et un deuxième circuit en roue libre (S6, D6) sont commandés de manière à toujours conserver un état non conducteur, un premier circuit en roue libre (S5, D5) est commandé de manière à toujours conserver un état conducteur, et le circuit d'isolation par couplage optique est commandé de manière à conserver un état conducteur synchrone avec les premier et deuxième circuits de commutation ; dans un demi-cercle de distribution de courant négatif, le premier circuit de commutation, le deuxième circuit de commutation et le premier circuit en roue libre sont commandés de manière à toujours conserver l'état non conducteur, le deuxième circuit en roue libre est commandé de manière à toujours conserver l'état conducteur, et le circuit d'isolation par couplage optique est commandé de manière à conserver un état conducteur synchrone avec les troisième et quatrième circuits de commutation. Le procédé réduit les pertes de commutation et de conduction.
