Abstract
(EN)
Provided is a power control apparatus for high frequency dielectric heating, which is not affected by magnetron types, fluctuations of characteristics, power supply voltages and the like. The power control apparatus is provided with input current detecting sections (71, 72) for detecting an input current to an inverter circuit (10), which rectifies (31) an alternating current power supply voltage (20) and converts it into high-frequency power by performing high-frequency switching. A switching frequency control signal (92) wherein input current waveform information (90) from the input current detecting section and power control information (91) are mixed, is converted into a drive signal of semiconductor switching elements (3, 4) of the inverter circuit.

L'invention concerne un appareil de commande de puissance conçu pour un système de chauffage diélectrique haute fréquence sur lequel le type de magnétron, les variations de caractéristiques, les tensions d'alimentation ou analogue n'ont aucune influence. Cet appareil de commande de puissance comprend des sections de détection de courant d'entrée (71, 72) conçues pour détecter un courant d'entrée injecté dans un circuit inverseur (10), une tension d'alimentation en courant alternatif (20) étant corrigée (31) et convertie en puissance haute fréquence au moyen d'une commutation haute fréquence. Un signal de commande de fréquence de commutation (92), qui combine des informations (90) sur la forme d'onde du courant d'entrée fournies par la section de détection de courant d'entrée et des informations de commande de puissance (91) est converti en un signal d'attaque pour les éléments de commutation à semi-conducteurs (3, 4) du circuit inverseur.
