Microwave oven power supply and oscillator therefor

摘要: The specification presents an improved microwave oven power supply of the type which contains a transformer having primary and high voltage secondary winding, rectifier capacitor combination connecting winding to magnetron control switching means, such as Triac, is included in series circuit with current through primary. In therewith pulse generator employed operation means; providing pulses means essentially turn on off for predetermined intervals. improvement provides that single member accessible user, varies or adjusts width duration applied switch concurrently time base period reoccur, suitably expanding expansion base, vice versa. additional novel synchronizer AND gate are connected so concurrence synchronizing from must coincide before Triac may be started.
