I am using the 2SD, because it’s what i had on hand salvaged at the moment, since i fried my 2dd1878 transistor i was using. Then if the recovery can exceed the power input, then when using a battery for input, we may be able to swap batteries and gain charge in both batteries, which is why the tests to gain the most efficiency with this type of split negative setup. It is possible though that the older types will have a low value hFE so you would need to pre-bias the base. Jual ic tda b ic vertical deflection output deskripsi.

Another advantage would be the lower dissipation in such transistor due to the much lower saturation voltage. In case diagnosis circuit that detect unusual case is operated, npn transistor q1 is turned on.

I am now using my watt boost converter as the input power supply, so i can raise the voltage even further to test any efficiency increases. Your thoughts on these results are very welcome, not much interest at the other forum apparently. Thanks for showing these results. With a more modern switching transistor like ZTX for instance, the DC current gain ranges from to for around 0.

The objective is to charge the battery with the highest throughput efficiency. I’ve just about maxed out my boost converter at 90 volts. Also, you use a relatively good HV switching transistor, the only ‘issue’ I can mention would be its rather low hFE, DC current gain of 8 to 10 at around 1 to 4A collector current range, from data sheet: The main function of this circuit setup, is to pulse charge a battery using the current flowing through an oscillator coil.

Latest test using Though the main goal is an efficient charger that can make a battery last for many more cycles than a typical, off the shelf charger. Hi stiplanet, Thanks for the reply.
