摘要： The variable impedance circuit comprising the invention provides a circuit having an impedance which varies in response to an input signal. The invention utilizes a control circuit which samples the load current and compares it to the demand signal to generate a control signal. The control signal is coupled to a load driver circuit to cause the required current to flow through this circuit. The load driver circuit and one or more substantially identical load circuits are series coupled to form a variable impedance circuit having the desired voltage and current capability.

摘要： Control circuit for controlling a switched converter generating an output voltage which is independent of variations of the input voltage. For this purpose, a forward control is used with a sawtooth voltage of which both the variation during the pulse duration of the pulses applied to the switch of the converter and the slope are linear functions of the input voltage and of an adjusting voltage. The output voltage is proportional to the adjusting voltage. This can be derived from the output voltage by means of a feedback coupling.

摘要： A circuit is provided, including first and second input terminals (110, 112) an output terminal (114), a DC-to-DC converter (120), and a trifilar choke (130) including a first inductor (140) connected between the first input terminal (110) and a first input terminal (150) of the converter (120), a second inductor (142) connected between the second input terminal (112) and a second input terminal (152) of the converter (120), and a third inductor (144) connected between the output terminal (114) and an output terminal (154) of the converter (120). The converter (120) is configured to convert a first voltage (V1) received at its first and second input terminals (150, 152) to a second voltage (V2) at its output terminal (154) higher than the first voltage (V1). The first, second and third inductors (140, 142, 144) are wound on a same core, mutually coupled and arranged such that currents common to the first and second inductors (140, 142) and currents common to the second and third inductors (142, 144) are blocked or attenuated. A current-limiting device, battery modules and a method of noise filtering are also provided.

The control circuit is configured to sense the first input DC voltage and the second input DC voltage and to enable the first input circuit and disable the second input circuit in response to the first input circuit having the highest input DC voltage to substantially prevent current from back feeding to the first input circuit from the second input circuit. The control circuit is also configured to enable the second input circuit and disable the first input circuit in response to the second input circuit having the highest input DC voltage to substantially prevent current from back feeding to the second input circuit from the first input circuit.
