摘要： An output voltage detecting circuit includes a conducting structure, a voltage regulator, a first resistor and a second resistor. The conducting structure includes a power output return terminal, a first contact and a second contact. A compensating voltage is generated between the first and second contacts when an output current flows through the first and second contacts. The voltage regulator adjusts a first current according to a voltage across a first circuit terminal and the ground terminal of the voltage regulator, thereby generating a detecting signal according to the first current. An output voltage across the positive power output terminal and the power output return terminal is subject to voltage division by the first and second resistors to generate a divided voltage. The voltage across the first circuit terminal and the ground terminal of the voltage regulator is equal to a difference between the divided voltage and the compensating voltage.

摘要： Techniques are disclosed to control output power from a switching power supply. A sample power converter controller circuit includes a control circuit coupled to be coupled to a switch. The control circuit includes a current sense circuit to be coupled to a primary winding of an energy transfer element coupled to the switch. The control circuit also includes a measurement circuit to be coupled to a secondary winding of the energy transfer element. A feedback circuit is also included and is coupled to the control circuit and coupled to receive a feedback-signal derived from an output of a power converter. The feedback circuit is coupled to output a signal to the measurement circuit. An output of the measurement circuit and an output of the current sense circuit are coupled to control a switching of the switch to regulate a combination of an output voltage and an output current of the power converter. A combination of the output voltage and the output current corresponds to at least one of a regulated output region and an unregulated output region. At least one of the unregulated output regions is a self protection auto-restart region. Within at least one unregulated output region the power converter controller circuit provides continuous output power at a substantially maximum output power of the power converter. Each output region corresponds to a magnitude and duration of the feedback signal.

摘要： A switching mode power supply (SMPS) with an active load detection function which supplies AC power input to a primary coil of a transforming element, then to a secondary coil of the transforming element, and then rectifies and outputs the AC power is provided. The SMPS comprises a controlling unit for controlling switching frequency by changing the time constant of a switching unit depending on the current and reducing the amount of power supplied to the primary coil of the transforming element. The current at a terminal of a resistor can be controlled under a cross condition, and the current flowing to the resistor can be controlled when in a normal state, thereby preventing energy loss which always occur in the resistor. The switching frequency during a standby state can be reduced to reduce switching loss.

摘要： An energy saving DC-DC converter circuit is disclosed having two energy efficient means which operate in tandem, an energy conserving means (30, 8, 1) and a voltage doubling means (26). These energy efficient means are applied in combination with elements commonly found in DC-DC converter circuits, namely an AC voltage generator (2), a transformer (3) for stepping up the generated AC voltage, and means (31) for storing the converted DC voltage. The energy conserving means is connected to the DC voltage storage means (31). It comprises a resettable inhibit circuit (1) which cuts off the provision of DC voltage for conversion for a predetermined interval when the output of the converter exceeds a predetermined level. The voltage doubling means is reponsive to outputs of the inhibit circuit (1) of the energy conserving means and the AC voltage generator (2). It provides a phase inverted waveform of the generated AC voltage on one of two leads to the AC voltage step-up transformer (3).
