Title: Minimizing lamp flicker and blower speed variation in  a microwave oven employing duty cycle power level control
Inventor: HARMON LARRY R
IPC: H05B6/68
Filed: 1978-04-13
Granted: 1981-01-13
Abstract: ABSTRACT OF THE DISCLOSURE      A microwave oven circuit includes a magnetron power transformer and a duty cycle controlled switching element connected to periodically energize the power transformer from an AC power source.  Due to the effects of power source loading, the available AC voltage drops during those intervals when the power transformer is energized.  This undesirably causes cyclical variation in the operation of certain constantly energized load devices such as the oven lamp and the motor for the blower which provides cooling air for the magnetron.  To minimize the undesirable voltage variation, a low voltage secondary winding is connected in series with the constantly energized load device and properly phased to provide a voltage boost upon energization of the power transformer.  Preferably, the low voltage secondary winding is an otherwise unused winding originally intended to be a magnetron filament winding.  As a result, very little additional cost is involved.

Abstract: CONTROL SYSTEM FOR TWO-PHASE REVERSIBLE MOTOR            Abstract:      By closing a series-connected first solid state switch, such as a triac, AC line voltage is applied directly to the first of two field windings of a two-phase reversible AC induction motor to drive the motor in one of its two directions.  The shifted phase voltage, appearing at the other or second field winding, has a magnitude of about twice that of the line voltage and is employed to supply gate current to the first solid state switch over a cross-coupling circuit.      Conversely, when motor rotation in the opposite direction is desired a second solid state switch or triac is rendered conductive to apply the AC line voltage directly to the second field winding, the gate current for the second solid state switch being derived from the high magnitude shifted voltage appearing at the first winding.  Since the gating voltage is phase displaced (by approximately 90°) with respect to the AC voltage applied to the main terminals of the gated triac, the gating voltage will have a relatively high instantaneous amplitude each time the applied AC voltage crosses its a-c axis, namely, goes through zero amplitude.  As a result, the triac will be immediately regated at the start of each half  cycle. In effect, the triac will be DC gated.
