Efficiency is now The 23 kOhm base bias resistor could be in the kOhm range or so and the 15 kOhm could be in the kOhm range or so I think. D sanyo semicon device, d datasheet elcodis. I will look at what transistors i can get, that are similar to what you describe, any improvements in efficiency is what i need. General description highvoltage,highspeed switching npn transistors in a plastic envelope datwsheet integrated efficiency diode,primarily for use in switching power circuites of colour.
It is possible the DC pre-bias role of the 23 kOhm resistor would become obsolote i. Ics for audio common use an technical information continued volume control continued alternative responses of volume control may be obtained by addition of a diode across the resistor datashert.

Latest test using On this latest test, using D nte equvilent nte npn horizontal deflection transistor nte silicon npn transistor color tv horizontal deflection output.
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.

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.
I also have a capacitor in parallel datassheet each of the resistors shown in the circuit drawing, it helps to adjust frequency and lower input.

Hola a todos necesito la hoja de datos del transistor de salida horizontal d, si alguien tiene estos datos por favor muchas gracias.
I do not think either that the built in diode would be datashdet issue. With a more modern switching transistor like ZTX for instance, the DC current gain ranges from to for around 0.

The main function of this circuit setup, is to pulse charge a battery using the current flowing through an oscillator coil. When the transistor is off, the built in diode between the collector and emitter immediately becomes reverse biased from the DC supply dataasheet appearing across it and the kickback pulse flyback coming from the coil will also appear in reverse direction.
The objective dahasheet to charge the battery with the highest throughput efficiency.
The tl device provides for pushpull or singleended output operation, which can be selected. The actual voltage through oscillator circuit is D datasheet color display horizontal deflection output. These tests are tuned to use close to the same input wattage, by adjusting resistor values in oscillator circuit. Also had to wire another neon in series with neon across transistor collector, because the higher voltage was causing it to conduct.

2sc1878 It is possible though that the older types will have a low value hFE so you would need to pre-bias the base. I find these results promising, i will continue to raise the voltage by 10 volt increments and tune and share the data with you folks. D datasheet color display horizontal deflection output, 2sd datasheet, d pdf, d pinout, equivalent, data, d circuit, d schematic. Another advantage would be the lower dissipation in such transistor due to the much lower saturation voltage.

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. I think this boost converter can only reach around 90 volts though. 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: Actual voltage through oscillator is When using an input voltage of In case the coil has conditions for ringing like an LC circuit, then the diode may have a chance to conduct, this is not the likely case in your circuit.
