摘要： There are provided a DC-to-DC converter control circuit capable of implementing compatibility between low ripple voltage characteristics, and stable and fast response characteristics at the time of a sudden change in load, and a DC-to-DC converter control method using the same. An add-up signal of an output voltage signal obtained according to an output voltage of a DC-to-DC converter, and an AC current signal obtained according to an AC current component of a coil current is outputted from an arithmetic circuit, and the add-up signal is compared with a reference signal by a comparator. Switching control of the DC-to-DC converter is executed according to a result of comparison by the comparator. Even if an equivalent series-connected resistance ESR of a smoothing capacitor, connected to an output terminal of the DC-to-DC converter, is reduced, and a voltage ripple becomes very small in value, it is possible to detect variation in a coil current of the DC-to-DC converter, thereby obtaining an add-up signal obtained by adding a variation component of the coil current to the output voltage. By comparing the add-up signal with the reference signal, variation in the coil current, due to a change in load, can be captured with reliability.

摘要： Multiple lighting apparatus coupled together to form a lighting network, in which operating power is efficiently provided throughout the network based on a distributed DC voltage or a distributed AC voltage. Based on various power driver configurations, each lighting apparatus incorporates one or more power drivers for one or more LED-based loads. In one example, a controlled predetermined power is provided to a load without requiring any feedback information from the load (i.e., without monitoring a load voltage and/or load current). In another example, a “feed-forward” power driver for an LED-based light sources combines the functionality of a DC-DC converter and a light source controller, and is configured to control the intensity of light generated by the light source based on modulating the average power delivered to the light source in a given time period, without monitoring and/or regulating the voltage or current provided to the light source. In various examples, significantly streamlined circuits having fewer components, higher overall power efficiencies, and smaller space requirements are realized.

摘要： A method and circuits for improving the inductive DC converter delivery of regulated current into the load(s), where the inductive DC converter provides the output voltage to an ensemble consisting of the load(s) and a current source or a current source circuit connected in series with the load. The load current is controlled by the current source or the current source circuit in series with the load and not by the inductive DC converter, which only provides the voltage and power required at the output, without directly controlling the load current. The inductive DC converter can operate under much more relaxed specs, while the load current regulation is much tighter, being current source controlled.

摘要： Active power filters and methods control and regulate the input current drawn from an electric power bus to a DC level. Load current fluctuations and ripple current reflected back to the electric power bus are significantly reduced or substantially eliminated. A switch mode power converter with a very low bandwidth output voltage regulation control loop uses input voltage feedforward, output load feedforward, and output voltage feedforward to provide a regulated DC input current significantly attenuating input ripple current drawn from the electric power bus.

摘要： A DC/DC converter has an output voltage and sources an output current to a load. The DC/DC converter includes an error amplifier with a reference input and a summing input. The reference input is electrically connected to a reference voltage. The summing input is electrically connected to the output voltage and the output current. The summing input is configured for adding together the output voltage and the output current. The error amplifier issues an error signal and adjusts the error signal dependent at least in part upon the output voltage and the output current. A comparator receives the error signal. The comparator has a ramp input electrically connected to a voltage ramp signal. The comparator issues an output signal that is based at least in part upon said error input. A power switch has an on condition and an off condition, and supplies dc current to the load when in the on condition. The power switch has a control input electrically connected to the comparator output signal. The power switch is responsive to the control input to change between the on condition and the off condition to thereby adjust the output current of the DC/DC converter.
