    • A circuit includes phase windings, a power switch circuit comprising at least one power switch at a midpoint of the phase windings, a direct current (DC) supply circuit at the midpoint of the phase windings, and one or more non-collapsing DC power supply components to prevent the DC power supply from collapsing when the at least one power switch is on and conducting during one or more portions of a cycle. The one or more non-collapsing DC power supply components each may include one or more of a tap from one of the phase windings electrically connected to the DC power supply, a secondary phase coil winding connected to the DC power supply to power the power supply, one or more resistors between the one of the phase windings and the power switch circuit, one or more Zener diodes between one of the phase windings and the power switch circuit, and/or an electrical component to create a voltage drop between one of the phase windings and the power switch circuit to prevent the power supply from collapsing when the at least one power switch in the power switch circuit is on and conducting.
    • 电路包括相绕组,功率开关电路,其包括在相绕组中点处的至少一个功率开关,在相绕组中点处的直流(DC)电源电路和一个或多个非塌陷直流电源 组件,用于在一个循环的一个或多个部分期间当所述至少一个电源开关接通并导通时防止所述直流电源塌陷。 所述一个或多个非崩溃的DC电源组件各自可以包括从与所述DC电源电连接的所述相绕组中的一个的抽头中的一个或多个,连接到所述DC电源以为所述电源供电的次级相线圈绕组 相位绕组和功率开关电路之一之间的一个或多个电阻器,一个相绕组和功率开关电路之间的一个或多个齐纳二极管和/或电气部件,以在其中的一个之间产生电压降 相绕组和电源开关电路,以防止电源开关电路中的至少一个电源开关导通时电源塌陷。
