摘要： This invention relates to a control circuit for the closed-loop control of an output voltage of a primary-controlled switched-mode power supply as well as an associated method. The switched-mode power supply comprises a primary-side switch and a transformer with at least one auxiliary winding in which an auxiliary voltage is induced after opening the primary-side switch. The voltage induced in the at least one auxiliary winding provides the basis for the measurement voltage passed to the control circuit and for the supply voltage of the control circuit. The invention also refers to an associated switched-mode power supply. In order to overcome the problems of known control circuits and to provide an improved control circuit for a primary-controlled switched-mode power supply, which can be constructed with increased control accuracy, but nevertheless with a small size and low component costs, the control circuit comprises a measurement voltage connection for connection to the measurement voltage and a supply voltage connection separate from same for connection to a supply voltage which is produced from the auxiliary voltage.

摘要： A circuit and corresponding method for reducing standby power and improving no-load to full-load regulation for ringing choke converters by maintaining a reduced duty cycle, with longer off time at no-load, while maintaining the output voltage swing closer to the full-load level. This reduced duty cycle prevents the output voltage from swinging high with respect to the full-load level, thereby providing good no-load and full-load output regulation in open feedback loop systems. The circuit and method provides very low no-load switching frequency and duty cycle by increasing the off time of the main switch through use of a turn off transistor driven by a zener diode, thereby maintaining conduction even with a very small control current and prolonging the off time of the main switch. The circuit and method achieves the benefits preferably using only less costly basic discrete converter components instead of more costly integrated circuits.

摘要： A wide-range compatible switching power supply circuit employs switching frequency varying control and allows enhancement of its AC to DC power conversion efficiency when a large AC input voltage is used. A coupled resonant circuit employing electromagnetic coupling by an isolation converter transformer is formed by providing a series resonant circuit both on the primary side and on the secondary side of the transformer. In order to achieve a unimodal output characteristic in the coupled resonant circuit, the length of a gap formed in a core of the isolation converter transformer is set to about 2.0 mm, and a coupling coefficient is set to about 0.8 or less. Thus, the switching frequency variable control range can be narrowed, which allows a wide-range compatible configuration. In addition, resonant frequencies of primary-side and secondary-side resonant circuits are set so that a requisite phase shift arises between a primary-side series resonant current and a secondary-side rectified current at least when an AC input voltage is 100 V and the load power is the maximum load power. Thus, the AC to DC power conversion efficiency when the AC input voltage VAC is 230 V can be enhanced.
摘要翻译：宽范围兼容的开关电源电路采用开关频率变化控制，并且当使用大的AC输入电压时，可以提高其AC至DC功率转换效率。通过隔离变换器变压器采用电磁耦合的耦合谐振电路通过在变压器的初级侧和次级侧上提供串联谐振电路而形成。为了在耦合谐振电路中实现单峰输出特性，形成在隔离变换器变压器的磁芯中的间隙的长度设定为约2.0mm，耦合系数设定为约0.8或更小。因此，开关频率可变控制范围可以变窄，这允许宽范围的兼容配置。此外，初级侧和次级侧谐振电路的谐振频率被设定为至少在AC输入电压为100V时，在初级侧串联谐振电流和次级侧整流电流之间产生所需的相移，负载功率是最大负载功率。因此，可以提高交流输入电压VAC为230V时的交流对直流电力转换效率。

摘要： A high voltage power supply apparatus and a method of correcting current output from the high voltage power supply apparatus. The high voltage power supply apparatus includes a switching unit; a transformer; a pulse width modulation signal processing unit, which receives a pulse width modulation signal changed for environmental conditions, converts the received pulse width modulation signal into a direct current (DC) voltage, and outputs the converted signal as a reference signal; a drive control signal generating unit, which compares an output current signal output from the transformer with the reference signal, and outputs a drive control signal to drive the switching unit; and an output current detecting unit, which detects the output current signal. Accordingly, the magnitude of current output from the high voltage power supply apparatus can vary according to environmental conditions and the current can be uniformly output without an output error.
