摘要： A controller is described, which is particularly suited for a power supply with switching elements (S1, S2), such as a switching mode power supply. The controller comprises a logical unit (18) which calculates a binary state value Z k by a first logical operation from a binary input value I and a prior binary state value Z k- 1 . The logical unit further calculates a binary output value Y by a second logical operation from the binary input value I and the binary state value Z k . In this way, fast and efficient fully digital control may be realized especially for a switching mode power supply, where the binary input value I is a comparator value and the binary output value Y is used to drive the switch elements (S1, S2). An adaptation unit (20), which may be a signal processor, determines the logical operations and delivers them to the logical unit (18) during operation of the controller unit (16).

摘要： A description is given of a power supply unit, an X-ray device having a power supply unit, and a method of controlling a power supply unit. In order also to control non-linear control paths, such as of a power supply unit operated with mixed-mode modulation, it is proposed that the control device be designed as a digital control device which calculates at least one correcting variable. The control device processes at least a first actual value U out , which depends on the output voltage. A time difference value is calculated from two sample values of the first actual value U out and is multiplied by a first controller coefficient K out . The value of the first controller coefficient can in this case change as a function of the operating point of the power supply unit.

摘要： Two proposals are made for power supply systems comprising at least one resonant inverter and one control unit. According to the first proposal the power supply system comprises two inverters and produces two output voltages, the control circuit processing as an actual value on the one hand the sum of and on the other hand the difference between the two output voltages. According to the second proposal a control circuit does not directly process the controlled variables for a power supply system comprising at least one inverter, but difference units for controlled variables determine the deviations from a preceding sampling instant and these difference values are processed. Also the correcting variable calculated in this way is a difference value which is converted into a correcting variable value by a correcting variable summing unit. The two proposals can be advantageously combined. As an important improvement is proposed the use of a limiting controller which generally becomes active in case of imminent transgression of a maximum value and which limits the actuation. The control circuit is preferably used as a digital control circuit for a state space control.
摘要翻译：对于包括至少一个谐振逆变器和一个控制单元的电力供应系统提出了两个建议。根据第一个提议，电源系统包括两个反相器并产生两个输出电压，一方面将控制电路作为实际值进行处理，另一方面是两个输出电压之间的差值。根据第二方案，控制电路不直接处理包括至少一个逆变器的电源系统的受控变量，但是用于受控变量的差分单元确定与先前采样时刻的偏差，并且处理这些差值。此外，以这种方式计算的校正变量是通过校正变量求和单元被转换为校正变量值的差值。这两个方案可以有利地组合。作为重要的改进，提出了一种限制控制器的使用，该限制控制器通常在即将发生最大值并且限制致动的情况下变得有效。控制电路优选地用作用于状态空间控制的数字控制电路。
