摘要： A step-down converter includes a self-conducting switching transistor (T1) and an inductance (L) located in a series arm, and a freewheeling diode (DF) located in a shunt arm. The switching transistor (T1) is controlled by a control transistor (T2). The control transistor supplies a blocking voltage, which is generated by a Zener diode (D1) in the series arm, to the switching transistor (T1) once a maximum value for a current (IL) in the series arm has been reached.

摘要： A power converter for coupling an energy source to a load device comprising a selectively coupled output stage to deliver energy from an energy source to a load device, a controller coupled to the output stage, an output stage, a capacitive element coupled to the output terminals, a rectifying element, and a switch responsive to a control signal from the controller. The rectifying element and switch are coupled to the inductive and capacitive elements. The controller is responsive to input signals for generating the control signal to open the switch in a first state and close the switch in a second state. The input signals to the controller produce one or more output voltages across the output terminals, an input voltage across the input terminals, a selectable reference voltage and a feedback signal measured with respect to the inductive element.

摘要： A DC-to-DC converter has a pulse width modulator PWM) and a hysteretic (ripple) modulator. For low current loads, the hysteretic modulator is selected; for high current loads, the PWM is selected. A mode selection switch senses the polarity of the switched output voltage at the end of each switching cycle. If the polarity changes from one cycle to the next, the mode may be instantly changed to the other mode. Counters are used to record the polarity at the end of each cycle and switching from one mode to another can be delayed by the counters to prevent changing modes based on spurious output voltage fluctuations.

摘要： An alternator system (50, 52) that, in one aspect, utilizes a Lundell style alternator that is augmented by power electronic switching components (62) in the output section. In one embodiment, some of these power switching embodiments employ a scaling of stator turns and wire size to achieve the superior performance at higher speeds. The alternator system provides significantly enhanced power capability above idle as compared with classical Lundell alternator systems using Lundell alternators of the same size that are designed with the same power capability at idle. In one preferred dual voltage embodiment, a power switch (semi-conductor) connects the alternator output directly to the low voltage load at low engine speeds and when the power switch is nullopenednull at higher speeds, the alternator's power is channeled to the higher voltage. In a 14-volt/42-volt dual-voltage system, this arrangement provides triple the alternator's power capability at high speeds as compared to a conventional unenhanced capabilities of the altenator system of the present invention are accomplished without increasing the alternator size or required current capacity and without using high frequency semiconductor power modulation (106).

摘要： A switching regulator connectable to a DC power supply includes a power switch coupled between a first node and an output node and having a control gate. An output voltage feedback circuit is coupled between the output node and a feedback node. A self-oscillating power switch control circuit is coupled to the first node, the feedback node, and the power switch control gate. The power switch control circuit compares a feedback voltage to a reference voltage and provides a first control voltage to the power switch control gate when the reference voltage exceeds the feedback voltage to turn on the power switch to raise the output voltage, and a second control voltage to the power switch control gate when the feedback voltage exceeds the reference voltage to turn off the power switch to lower the output voltage.
