Inverter power supplies utilizing IGBTs for microwave ovens, developed in 1988, have been being improved for these several years in order to progress there many good performances such as low weight, compact size, power source flexibility and high controllability.
A new cooking power control function “High Power Sprinter” has been developed for additionally improving cooking performance of micro wave ovens. The new function has to novel and superior techniques, a starting output power sequential control technique and an instantaneous peek power suppressing skill, in order to simultaneously realize high micro wave output power and high reliability of micro wave ovens.
Owing to a new auto cooking system using the new function having above novel skills, additional cooking performance improvements of micro wave ovens have been achieved. Especially cooking performances of speed cooking and energy saving are attractive futures in view of future cooking appliances' trends.
