    Abstract: The present invention relates to a digitally controlled switched-mode power supply, wherein a switched-mode power supply is provided with a control circuit, which comprises a signal amplifier unit able to receive digital signals or analog signals and a switching controller able to receive the signals. The switching controller uses the signals to produce a clock signal, after which the clock signal is output, whereupon the signal amplifier unit feeds a signal back to control the switching controller. The signal amplifier unit is provided with at least one amplifier element, and when the amplifier element receives a digital signal or analog signal, then the signal is transmitted to the switching controller. Accordingly, the control circuit achieves the effectiveness to not only receive and transmit digital signals, but also receive and transmit analog signals, and is thus provided with the advantage of enormous flexibility.

    Abstract: A method an apparatus to dynamically modify the internal compensation of a low drop-out (LDO) linear voltage regulator is presented. The process involves creating an additional equivalent series resistance (ESR) from an internal circuit. The additional ESR of the internal circuit is sufficient to ensure DC output stability. This allows the ESR of the output capacitance to be reduced to zero if desired, for improved transient response. The zero induced by the ESR of the internal circuit is frequency compensated, so that it tracks the position of the output pole as the load varies.

    Abstract: The present invention provides a primary-side flyback power converter that supplies a constant voltage output and a constant current output. To generate a well-regulated output voltage under varying load conditions, a PWM controller is included in the power converter in order to generate a PWM signal controlling a switching transistor in response to a flyback voltage sampled from a first primary winding of the power supply transformer. Several improvements are included in this present invention to overcome the disadvantages of prior-art flyback power converters. Firstly, the flyback energy of the first primary winding is used as a DC power source for the PWM controller in order to reduce power consumption. A double sample amplifier samples the flyback voltage just before the transformer current drops to zero. Moreover, an offset current is pulled from a detection input of the double sample amplifier in order to generate a more accurate DC output voltage. The offset current is generated in response to the temperature in order to compensate for temperature-induced voltage fluctuations across the output rectifier. Ultimately, in order to maintain a constant output current, the PWM controller modulates the switching frequency in response to the output voltage.

    Abstract: A PWM controller according to the present invention provides a technique to control the output voltage and output current of the power supply without the feedback control circuit in the secondary side of the transformer. In order to achieve better regulation, an adaptive load and a feedback synthesizer are equipped into the PWM controller, which associated with the auxiliary winding of the transformer regulate the output voltage of the power supply as a constant. Furthermore, a programmable power limiter in the PWM controller controls the power that is delivered from the primary side to the output of the power supply. The threshold of the power limit is varied in accordance with the change of output voltage. Because the output power is the function of the output voltage of the power supply, a constant current output is realized when the output current of the power supply is greater than a maximum value.

    Abstract: A pulse width modulated soft-switching power converter has a transformer with a primary winding and a secondary winding, a secondary circuit coupled to the secondary winding, and a pair of main switches and a pair of auxiliary switches coupled to the primary winding. The main switches and auxiliary switches intermittently conduct an input voltage source to the primary winding of the transformer to operate the soft-switching power converter in four operation stages in each switching cycle. The main switches conduct the input voltage source to the transformer in a first operation stage. In a second operation stage, the conduction is cut off. The transformer operates as an inductor with the auxiliary switches switched on under zero-voltage or zero-current switching mode in a third operation stage. In the fourth operation stage, auxiliary switches are switched off to achieve zero-voltage transition.
