Abstract

Perfeccionamientos introducidos en equipos electrónicos para regulación de tensión alterna en configuración directa sumadora mediante conmutación seminatural. La invención refiere a estabilizadores rápidos (tiempo entre conmutaciones inferior al semiciclo de red) de tensión alterna con tomas diferenciales en configuración directa sumadora para reducir en la red eléctrica perturbaciones lentas (caídas, sobretensiones y desequilibrios) y perturbaciones rápidas (caídas y sobretensiones breves, parpadeo o "flicker" y armónicos). La reducción conseguible en las rápidas aumenta con la frecuencia de conmutación. Para aplicarlos con seguridad en elevadas potencias y frecuencias, la conmutación de los semiconductores en los cambios de toma debe eliminar solicitaciones extremas de tensión, corriente y potencia. Sobre la conmutación básica de Burany (1989) se consiguen mejoras mediante un filtro de entrada y mediante secuencias de conmutación ajustadas selectivamente al estado de tensión o/y corrientede la carga, todo ello en diversas configuraciones del circuito principal.Refinements introduced in electronic equipment for alternating voltage regulation in direct summing configuration through seminatural switching. The invention relates to fast stabilizers (time between commutations less than the half-cycle of the alternating voltage) with differential sockets in direct summing configuration to reduce in the electrical network slow disturbances (falls, overvoltages and imbalances) and fast disturbances (short falls and overvoltages, flicker or "flicker" and harmonics). The attainable reduction in rapid increases with the switching frequency. To apply them safely at high powers and frequencies, the switching of the semiconductors in the tap changes must eliminate extreme stress, current and power solicitations. On the basic switching of Burany (1989) improvements are achieved by an input filter and by switching sequences selectively adjusted to the state of voltage or / and current of the load, all in various configurations of the main circuit.
