clamping circuit

clamping circuit

[′klamp·iŋ ‚sər·kət]
(electronics)
A circuit that reestablishes the direct-current level of a waveform; used in the dc restorer stage of a television receiver to restore the dc component to the video signal after its loss in capacitance-coupled alternating-current amplifiers, to reestablish the average light value of the reproduced image. Also known as clamp.

announces the introduction of the Sensepeek PCBite System, a professional yet affordable PCB testing apparatus with a system of repositionable fine-point spring-loaded probes, a large (8.3" x 11.7") metal baseplate, and four magnetic-base PCB holders for clamping circuit boards in a stable, fixed position.
The OH5 topology is shown in Figure 5(c) [8], which uses a switch and capacitor to form the bidirectional clamping circuit on the basis of the H5 topology, which greatly inhibits the leakage current, and improves the conversion efficiency.
It uses the clamp diodes or clamp bit capacitance to improve the midpoint clamping circuit, reducing the number of devices and uneven distribution of the loss.

In this paper, various clamping circuits are discussed to improve the performance of Fly back converter.
The clamping circuit recycles the energy stored in inductance [L.sub.r] (composition of leakage inductance of transformer and external discrete inductor), and in addition allows ZVS switching of [S.sub.prim1], [S.sub.prim2].
There is performed the simulation of this topology with standard RC clamp, and shortly described other clamping circuits. It makes sense to carefully analyze the efficiency of DFBI with lossless clamping circuits, as the efficiency of PV inverter is one of most important parameters for each PV application.
