Final Call: Shipping your Undetectable Knife Today

 

 

The legendary business magazine, Forbes, recently surveyed a group of scientists

and asked them what the most important tool for human survival was.

Their answer? This tool right here.

When we saw this study, we were thrilled.

At that exact time we came across it, we were making a new version of the very
same tool scientists claimed was the most important in human history.

It's a tool every single American alive should own.

Now, after several months of testing and developing, today is the day we release it to the public.
 

We know you're going to love this new tool. Even if you have one like it already.

However, the best reason to get it today isn't just because of how important it is...

It's because we're offering it at special holiday pricing.

Go here to see the new tool Forbes Magazine said is the most important tool in human history and get it for a great holiday price!

If the AC supply is fed via a transformer with a center tap, a rectifier circuit with improved harmonic performance can be obtained. This rectifier now requires six diodes, one connected to each end of each transformer secondary winding. This circuit has a pulse-number of six, and in effect, can be thought of as a six-phase, half-wave circuit. Before solid state devices became available, the half-wave circuit, and the full-wave circuit using a center-tapped transformer, were very commonly used in industrial rectifiers using mercury-arc valves. This was because the three or six AC supply inputs could be fed to a corresponding number of anode electrodes on a single tank, sharing a common cathode. With the advent of diodes and thyristors, these circuits have become less popular and the three-phase bridge circuit has become the most common circuit. Three-phase bridge rectifier uncontrolled Disassembled automobile alternator, showing the six diodes that comprise a full-wave three-phase bridge rectifier. For an uncontrolled three-phase bridge rectifier, six diodes are used, and the circuit again has a pulse number of six. For this reason, it is also commonly referred to as a six-pulse bridge. The B6 circuit can be seen simplified as a series connection of two three-pulse center circuits.
For low-power applications, double diodes in series, with the anode of the first diode connected to the cathode of the second, are manufactured as a single component for this purpose. Some commercially available double diodes have all four terminals available so the user can configure them for single-phase split supply use, half a bridge, or three-phase rectifier. For higher-power applications, a single discrete device is usually used for each of the six arms of the bridge. For the very highest powers, each arm of the bridge may consist of tens or hundreds of separate devices in parallel (where very high current is needed, for example in aluminium smelting) or in series (where very high voltages are needed, for example in high-voltage direct current power transmission).
