A Development Of The New Variable Power Microwave

The global competition of Microwave oven industry is getting stronger, and the profit of this industry is getting lower. Many factories try to develop creative products to make more profit and competition. A New type of Microwave Oven with changeable microwave output power is coming out in this period.LC circuit normally controls the microwave output level of tradition microwave oven, the output power is a constant, the adjustment of the power level is depending on the PCB or Timer controller which controls the Microwave ON and OFF. This type of microwave oven with changeable microwave output can make up with the shortcoming of the tradition microwave oven, it can cook almost all kind of different food, and the taste is coming to the best state, and also it can keep nutrition of the food. It is healthier and the cost is much lower than microwave oven with inverters, it is becoming a pioneer product of the microwave industry.The author find the a new method to realize the changeable microwave output power instead of inverters, which ban be realize changeable microwave output power by several groups of high voltage capacitors by a controller system. The author finds the difference between the normal microwave oven and the microwave with changeable microwave by analyzing the changeable microwave of competitors and microwave with inverter. The author study the high voltage matching system, research and analyze on how to realize the changeable capacitors and analyze the effect on the microwave output power and efficiency. Find the relationship between the microwave output, efficiency and the anode current. And finally develop a low cost and high value microwave oven with changeable microwave output, and improve the core competition ability of our company.
