Abstract

Circuito inversor de dos salidas, y circuito y procedimiento de control de la potencia de entregada en las salidas del inversor. Comprende medios para regular la potencia entregada, gobernando el ancho de pulso aplicado a unos semiconductores de potencia (S1-S6), y medios para gobernar el estado de dos conmutadores (R1, R2), de un puente en H trifásico, para alimentar a una única carga o a las dos simultáneamente. El circuito de control incluye medios generadores de referencias de corriente (3, 4 y 4"''), que generan (I1 e I2) proporcional a la potencia seleccionada. Incluye medios de comparación (5, 5"'') de (I1 e I2) con la corriente de la carga (IB1, IB2) para generar un pulso (P1, P2) cuya duración es igual al tiempo durante el cual (IB1 o IB2) es superior a (I1, I2). A partir de este pulso se gobierna la potencia. Los conmutadores (R1, R2) solo se activan cuando se activa o desactiva una carga (B1, B2). Cuando una única bobina demanda potencia se comparten los semiconductores de potenciay los conmutadores. El procedimiento actúa los semiconductores de potencia según un control de corriente'' de cancelación de tensión unipolar a frecuencia constante, con la particularidad de que cuando las dos bobinas demandan potencia a la vez, éstas se alimentan a idéntica frecuencia. Es preferentemente aplicable a cocinas de inducción.Inverter circuit with two outputs, and circuit and procedure for controlling the power delivered to the inverter outputs. It comprises means to regulate the power delivered, governing the pulse width applied to power semiconductors (S1-S6), and means to govern the state of two switches (R1, R2), of a three-phase H bridge, to feed a single charge or both simultaneously. The control circuit includes current reference generating means (3, 4 and 4 "''), which generate (I1 and I2) proportional to the selected power. It includes comparison means (5, 5" '') of (I1 and I2) with the load current (IB1, IB2) to generate a pulse (P1, P2) whose duration is equal to the time during which (IB1 or IB2) is greater than (I1, I2). From this pulse power is governed. The switches (R1, R2) are only activated when a load is activated or deactivated (B1, B2). When a single coil demands power, the power semiconductors and switches are shared. The procedure operates the power semiconductors according to a unipolar voltage cancellation current control '' at constant frequency, with the particularity that when the two coils demand power at the same time, they are supplied at the same frequency. It is preferably applicable to induction cookers.
