摘要： A control circuit for a polarity inverting buck-boost DC-DC converter, comprises an operational trans-conductance amplifier that has inputs to which a sensed voltage difference signal is applied and an output connected to an input of a voltage-to-duty-cycle converter. A compensation capacitance is connected between the output of the amplifier and a fixed supply terminal. The compensation capacitance comprises a first capacitor that is permanently connected between the output of the amplifier and the fixed supply terminal and a second capacitor that has a switched connection between the output of the amplifier and the fixed supply terminal. The first capacitor has a small capacitance compared to the second capacitor. The switched connection of the second capacitor is controlled by a continuous-discontinuous mode detection circuit.

摘要： The invention relates to methods of operating step-up DC voltage converters including a storage choke, the one terminal of which is connected to the input of the converter and the other terminal of which is connectable via a first controllable switch to ground and via a second controllable switch to the output of the converter; a clock outputting a first clock signal dictating the switching cycle of the converter, and a second clock signal, the cycle of which corresponds to that of the first clock signal; and a regulator circuit which regulates the voltage at the output of the converter to a setpoint value. In the methods the second switch is set ON at the end of the switching cycle during a constant time duration as dictated by the second clock signal and which as compared to the length of the switching cycles is short, whilst the first switch is set OFF, so that a transient flow of energy occurs from the output of the converter to the input of the converter. Due to this, the converter is always operable at a constant frequency independent of the load and thus permits simple noise filtering of the output voltage which is particularly of advantage in telecommunication applications. The invention relates furthermore to step-up DC voltage converters for implementing the method.
摘要翻译： 本发明涉及操作包括存储扼流器的升压DC电压转换器的方法，存储扼流器的一端连接到转换器的输入端，并且其另一端可通过第一可控开关连接到地并经由第二可控开关 可控切换到转换器的输出; 输出指示所述转换器的开关周期的第一时钟信号的时钟和第二时钟信号，所述第二时钟信号的周期对应于所述第一时钟信号的周期; 以及调节器电路，该调节器电路将转换器输出处的电压调节到设定值。 在这些方法中，第二开关在开关周期结束时在由第二时钟信号规定的恒定持续时间期间被设置为ON，并且与开关周期的长度相比较短，同时第一开关被设置为OFF， 以便从转换器的输出端到转换器的输入端产生瞬态能量流。 由此，转换器始终可以以与负载无关的恒定频率工作，并因此允许在电信应用中特别有利的输出电压的简单噪声滤波。 此外，本发明还涉及用于实现该方法的升压DC电压转换器。
