摘要： Standard configuration a.c. power transformer core sections are combined with standard configuration solenoid winding sections to provide a saturable core transformer which is arranged to be driven into saturation by applied alternating and direct current energy with the control of variations in flux changes up to saturation exercised by the direct current flow. A center tapped primary winding is arranged on an I-shaped stack of transformer iron laminations for full-wave excitation. A C-shaped stack of laminations is arranged adjacent to the I-shaped stack and separated by an air gap whereby the primary winding also serves as an input filter choke. The core structure is completed by an E-shaped stack of laminations arranged adjacent to the I-shaped stack and separated by another air gap. Two solenoid windings are arranged on the outer legs of the E-shaped stack and connected to a capacitor for resonating the overall ferroresonant transformer circuit arrangement. Secondary windings are also arranged on the outer legs and connected to a rectifying circuit for supplying direct potential to a load. A control winding is arranged on the central leg of the E-shaped stack of laminations. With this arrangement, the control winding is unaffected by variations in the a.c. voltage as they affect the flux changes in the transformer or in the frequency of the a.c. Regulation of the power supply is executed by direct current flow in the control winding. An adjustable resistor connecting the control winding across the output of the rectifier circuit is often all that is required to complete the circuit. In some applications, an amplifying circuit is used to provide a desired gain in the control winding circuitry.
摘要翻译：标准配置a.c. 电力变压器铁芯部分与标准配置电磁线圈绕组部分组合，以提供可饱和铁心变压器，其被布置成通过施加的交流和直流能量驱动到饱和状态，并且控制通量变化的变化直到达到直流电流的饱和。中心抽头的初级绕组被布置在用于全波激励的I形叠层变压器铁片上。叠置的C形叠层被布置成与I形叠层相邻并由气隙分开，由此初级绕组也用作输入滤波器扼流圈。芯结构通过邻近I形叠层排列并由另一个气隙隔开的E形叠层构成。两个螺线管绕组布置在E形叠层的外部支脚上，并连接到电容器上，以谐振整个铁磁谐振变压器电路装置。次级绕组也布置在外腿上并连接到整流电路，用于向负载提供直接电位。控制绕组布置在E形叠片叠片的中心支脚上。通过这种安排，控制绕组不受交流变压器的影响。电压，因为它们会影响变压器的通量变化，也可以影响变压器的频率。电源的调节由控制绕组中的直流电流执行。连接整流电路输出端的控制绕组的可调电阻通常都是完成电路所需要的。在一些应用中，放大电路用于在控制绕组电路中提供期望的增益。

摘要： Transformer for providing a regulated and filtered output voltage. Input voltage is applied to an input winding which is wound around two magnetic cores. One magnetic core saturates for part of each half-cycle of the induced alternating flux during normal operation. The other magnetic core does not saturate during normal operation and includes air gaps in the legs thereof. An output winding is positioned around the nonsaturating core and connected in parallel with a capacitor to form an output tank circuit resonant at the operating frequency of the transformer.

摘要： A current regulator to supply two balanced regulated currents of opposite polarity utilizes separate sum and difference currentsensing transformers to generate feedback control signals. These feedback signals control the operation level of a saturable reactor which regulates the drive signal to the output power transformer. Protection circuits responsive to the output voltage prevent it from exceeding predetermined critical levels.

摘要： A voltage regulator in which an inductor having a saturable core is connected in series with a capacitor, the output being taken from across the inductor. After startup, the combined effect of the input voltage and the capacitor cause the core of the inductor to periodically switch from a nonsaturated to a saturated condition and vice versa so that the impedance of the inductance switches correspondingly from a high to a low value. The result is a square wave voltage developed across the inductor that has a constant amplitude regardless of input voltage variations if the input frequency remains constant.
