Abstract: A power supply for providing a stable operating current to a magnetron-excited lamp. The power supply includes a DC to DC inverter for driving a primary winding of a high voltage transformer. The DC to DC inverter has a circuit including two pairs of switching elements for connecting a DC voltage supply to the primary winding. During each half of the switching cycle, one of the switching elements is pulse width modulated while the other remains on for a substantially fixed period of time. During the second half of the cycle, the remaining pair operates so that one switching device is on for a pulse width modulated period of time, and the other is on a substantially constant amount of time. The on time for the pulse width modulated switching elements is defined by an input voltage setting representing a desired brightness level for the lamp, the output magnetron current, and a representative of the integral of the current flowing through the primary of the inverter transformer.

Abstract: A circularly polarized microwave oven. Microwave energy is coupled from a waveguide above the ceiling to the cavity by a rotatable vertical probe. A strip transmission line closely spaced to the ceiling to limit radiation therefrom conducts the microwave current from the probe to a helical strip antenna radially offset from the axis of the probe. The helical strip antenna has a cylindrical segment which has a downward slope from its feed end to gradually increase the spacing between the cylindrical segment and the ceiling which functions as a ground plane. The increase in radiative efficiency around the cylindrical segment caused by increasing the spacing to the ceiling offsets the magnitude of the current traveling wave diminishing as a result of radiation losses. Accordingly, the magnitude of the X and Y electric vectors are substantially equal over a relatively wide angle thus defining circular polarization. Connected to the opposite end of the cylindrical segment is a flat or horizontal segment of the helical antenna. Rotation of the probe about its axis moves the helical antenna in a horizontal circular path thus further enhancing the heating uniformity.

Abstract translation: 圆极化微波炉。 微波能量通过可旋转的垂直探针从天花板上方的波导耦合到空腔。 与天花板紧密隔开以限制辐射的带状传输线将微波电流从探针传导到径向偏离探针轴线的螺旋条状天线。 螺旋带状天线具有圆柱形段，其从其进给端具有向下的斜面，以逐渐增加用作接地平面的圆柱形段和天花板之间的间隔。 由于通过增加到天花板的间距而引起的圆柱形段周围的辐射效率的增加抵消了由于辐射损耗而导致的当前行波的幅度的减小。 因此，X和Y电矢量的大小在相对较宽的角度上基本上相等，从而限定圆偏振。 连接到圆柱段的另一端是螺旋天线的平坦或水平段。 探针围绕其轴的旋转将螺旋天线移动到水平圆形路径中，从而进一步增强了加热均匀性。
