KS-003: Transformer Assemble IT and OT Transformer for Power Amplifier | كيف حالك يا أخي
In my previous article I have explained about the construction of a model transformer amps IT and OT. Because this type of current transformer is no longer sold in the market, then the only alternative must assemble transformer IT / OT itself if it will make the amps transformer. Here I will explain how to create a Transformer Manual based on experience in junior high I used to. Below is an example of factory-made wired doorbell transformer OT:
Actually wired doorbell not too difficult to assemble, just how to get a count of how many needs coil wire, number of coils, the size of the wire, and the cross-sectional area who used containers, must be designed appropriately beforehand. Proper design practically 90% of success. To produce the right design, you must first understand the two theories in this regard (sorry, do not mean to patronize, just another lesson to remember in junior high and high school ... hehehe), namely: Theory Voltage In Coils (basic references: Book Learning Electronics for JSS, R.Soenardi, the Three Ones, Solo, 1984). The theory is to determine: the number of windings, the magnitude of the wire, and the cross-sectional area containers in use in accordance with the power to be achieved. Faraday Indukstansi theory (basic wired doorbell references: Book 2 for high school Physics, Ganesha Exact Bandung, 1990). This theory is needed to determine the direction of winding.
As an illustration, here's my experience in the IT and assemble Transformer Transformer OT for amps that produce 100-200 watts of power are as follows (the following figures obtained from the calculation based on two theories above, I deliberately did not include the "paper work" perjitungannya, because besides too technical will also take up a lot of space):
How to Assemble IT TRANSFORMER: Set up e-mail insulated wire (khusu for coil) diameter of 0.2 mm along the 40 m. Prepare the transformer with 8 cm square cross-sectional area along the Iron E, or the size of the PSU transformer 500 mA. For simplicity's sake just buy a PSU transformer 500mA or can be taken from the former transformer 500mA AC-DC adapter that has been damaged. The PSU transformer coil is discharged wired doorbell and subsequently demolished house just taken Transformer (of plastic) and Iron E was alone. Start making the coil on the transformer wired doorbell house with 2 mm wire earlier email, the number of coil windings Primary = 200, the number of secondary coil windings = 2 x 80 CT. How to make a winding on transformer IT and OT should be done alternately between the Primary winding Secondary winding alternately overwrite each other. Namely: the first primary winding is made first to finish one layer then wrapped disposable plastic insulation, then overwritten on top of the secondary winding wrapped wired doorbell another layer continues to wear isolation, primary winding continues overwritten again ... and so on alternately until reaching 200 primary windings and 2 x 80 secondary winding. Direction primary and secondary windings must be opposite, which means that if the primary winding wired doorbell is made in a clockwise wired doorbell direction, then the secondary wired doorbell winding is made counter-clockwise, and vice versa. This is important because the main function is as an inverting transformer IT PHASE, then if one winding direction in doing so becomes wired doorbell "SE-PHASE" alias will not produce sound.

insha-allah I will present in a later paper pack. The principle is the same with the inverter using a transformer PSU 12v to 220volt or 12volt to 110volt. The key is how to get a PSU that has V transformer 12v primary and secondary V 42V. The voltage of the transformer wired doorbell is definitely NOT SOLD in the market. So should MAKE own Trafonya or mengumpar own. The trick is not too complicated khan (so remember lessons in junior high electro know about how to make a transformer wired doorbell ... he .. he ... he ...). For the transformer can be made of former PSU 500mA-1A (with kern 5cm square cross-sectional area). Due to technical scr count, to kern 5cm cross section will produce 1 volt per 10 coils (sorry deliberate calculation formula is not published here), the importance wired doorbell of the count of the number of primary winding (Lp) and the secondary coil (Ls) coil as follows: - Lp = 12volt = 12 x 10 = 120 loops - Ls (CT) = 2 x 42volt = 2 x (42 x 10) = 2 x 420 windings.
While Scheme Elektronisnya, please at googling a lot of variants, the popular Final with Tr Tr oscillator 2N3055 NPN combination of small type or IC (that popular with IC LM-741 or LM-555). Stay replaced his PSU Transformers Transformers homemade accordance with the above calculations. The amount of Ampere (would affect Watt output), depending on the size of the wire used.
I pingin welding transformer for the DC power from battery power, if now I have a car battery 12v/80A wired doorbell 3 pieces then I collated series so sya get 36v/80A voltage ... and I want to make a transformer with the input and output of 36v/80A lillitan secondary around 30V/96A, and then yes
