Un four à micro-ondes à chauffage uniforme/sélectif à haut rendement a été développé. Étant donné que l'amplificateur de puissance nécessite des caractéristiques de haut rendement pour fonctionner comme une source de micro-ondes, un substrat autonome en nitrure de gallium (GaN) a été appliqué dans cette étude. En appliquant un circuit de réglage harmonique, une puissance de sortie de 71 W et un PAE de 73 % ont été obtenus en fonctionnement pulsé, et une puissance de sortie de 63 W et un PAE de 69 % ont été obtenus en fonctionnement CW. De plus, nous avons fabriqué un prototype de module PA composé d'un oscillateur, d'un amplificateur pilote, d'un PA et d'autres circuits RF. La puissance de sortie était contrôlée par modulation de largeur d'impulsion pour maintenir un rendement élevé quelle que soit la puissance de sortie. Nous avons évalué la disposition des polarisations des antennes pour isoler chaque antenne. En supprimant les interférences de sortie provenant d'antennes adjacentes, il est possible d'irradier l'objet sur la surface supérieure de l'antenne, démontrant ainsi des caractéristiques de chauffage avec de petites irrégularités de température. Le prototype de four à micro-ondes a démontré avec succès un chauffage uniforme/sélectif.

Abstract: A high-efficiency uniform/selective heating microwave oven was developed. Because the power amplifier requires high-efficiency characteristics to function as a microwave source, a free-standing Gallium Nitride (GaN) substrate was applied in this study. By applying a harmonic tuning circuit, an output power of 71 W and PAE of 73% were achieved in pulsed operation, and an output power of 63 W and PAE of 69% were achieved in CW operation. Moreover, we fabricated a prototype PA module that consists of an oscillator, a driver amplifier, PA, and other RF circuits. The output power was controlled by pulse width modulation to maintain high efficiency regardless of output power. We evaluated the arrangement of antenna polarizations to isolate each antenna. By suppressing the interference of output from adjacent antennas, it is possible to irradiate the object on the top surface of the antenna, thereby demonstrating heating characteristics with small temperature unevenness. The prototype microwave oven successfully demonstrated uniform/selective heating.
