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) , 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.

The RCD clamping circuit consists of a fast recovery diode in series with a parallel combination of a capacitor and a resistor which is shown in Fig.3.1.
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.
The hydraulic clamping circuit
for the bed, or ram, has a separate hydraulic hose for direct control.
This requirement was implemented with an over-voltage clamping circuit
across the MOSFETs and a fast over-current shutdown.
