For microwave ovens, the transformer needs reducing the weight. The continuous adjustability of output power is also required to improve cooking performance. Recently resonant inverter type power supplies for microwave ovens have been examined, but the output power ability has not been examined in datail.
We studied the relation between circuit parameters and the characteristics of the power supply with a transformer that works also on resonant reactor. As a result the output of the power supply was related to the leakage inductance of the transformer.
Finally, we discussed about the experimental result using this instrument. The output of the power supply can be continuously controlled in the range of 10 to 100%. Furthermore, adoption of this inverter can reduce the weight of the power supply to about 2/3.
