Title
(EN) POWER CONTROL SOLUTION FOR REDUCING THERMAL STRESS ON AN INTERMITTENTLY OPERABLE CHIPSET CONTROLLING RF APPLICATION FOR COOKING
(FR) SOLUTION DE COMMANDE DE PUISSANCE POUR RÉDUIRE UNE CONTRAINTE THERMIQUE SUR UN JEU DE PUCES FONCTIONNANT PAR INTERMITTENCE COMMANDANT UNE APPLICATION RF POUR LA CUISINE
Abstract
(EN)
Control electronics may control power amplifier electronics associated with application of RF energy generated using solid state electronic components. The power amplifier electronics may be configured to control application of RF energy in an oven according to a cooking recipe at least in part based on a learning procedure that generates a power cycling between high and low powers when the learning procedure is executed. The control electronics may include processing circuitry configured to employ a thermal stress mitigation technique to control thermal stresses on the power amplifier electronics associated with the power cycling.

Une électronique de commande peut commander l'électronique d'amplification de puissance associée à l'application d'énergie RF générée à l'aide de composants électroniques à l'état solide. L'électronique d'amplification de puissance peut être conçue pour commander l'application d'énergie RF dans un four selon une recette de cuisine au moins en partie sur la base d'une procédure d'apprentissage qui génère un cycle de puissance entre des puissances élevées et basses lorsque la procédure d'apprentissage est exécutée. L'électronique de commande peut comprendre un circuit de traitement conçu pour utiliser une technique d'atténuation de contrainte thermique pour commander des contraintes thermiques sur l'électronique d'amplification de puissance associée au cycle de puissance.
