摘要： Dans un système onduleur résonnant et régulé pour fournir un courant continu à une charge, on élimine les larges oscillations de fréquence de fonctionnement requises pour compenser les variations de puissance par la commutation sélective de combinaisons d'étages/onduleurs résonnants parallèles à pondération binaire (ST-1 à ST-4). Les étages sont réglés à la même fréquence, mais chaque étage possède des caractéristiques de puissance différentes déterminées par la racine carrée du rapport C/L où C représente la capacitance de résonnance (46-1 à 46-4) et L l'amplitude de l'inducteur de résonnance (42-1 à 42-4 et 44-1 à 44-4). Pour une condition de puissance désirée, un circuit de réaction (19-27, 60) sélectionne un étage ou une combinaison d'étages et en commande la fréquence de fonctionnement, de façon que la fréquence de fonctionnement reste élevée à tous les niveaux de puissance.

摘要： In a regulated, resonant inverter system for supplying direct current to a load wide operating frequency swings required to compensate for output variations are eliminated by selectively switching combinations of binary weighted parallel resonant inverter stages (ST-1 to ST-4). The stages are tuned to the same frequency, but each stage has a different power capability determined by the square root of the ratio C/L, where C is the resonating capacitance (46-1 to 46-4) and L is the magnitude of the resonating inductor (42-1 to 42-4 and 44-1 to 44-4). For a desired output condition, a feedback circuit (19-27, 60) selects a stage or a combination of stages and controls the operating frequency thereof so that the operating frequency remains high at all power levels.

摘要： An inverter system has first and second resonating current sources (50-63, 70-83) which are resonant at the same frequency. The currents of the two sources are combined. At lower power levels, the currents are substantially out of phase and the frequency is adjusted. At intermediate power levels, the phases of the currents are adjusted and the frequency is fixed. At high power levels, the currents are substantially in phase and the frequency is adjusted.
