This circuit uses standard components and shows a method of indicating the fuse status of mains powered equipment while providing electrical isolation from the mains supply. A standard miniature low power mains transformer (e. g. with an output of around 6 V.... -
The timer IC(NE555) is wired as an ASTABLE MULTIVIBRATOR in this circuit. It will generate Alternating non sinusoidal output wave form at the instant we giving supply Voltage(12V). Thus primarily we generated Alternating Voltage from direct Current.... -
This power supply was designed for use with the Simple hybrid amp` published elsewhere in this issue. It is of course suitable for use in other applications as well. We`ve used a cascade generator for the 170 V, a switch mode supply for the 16 V, a series.... -
Tuned circuits consist of C4, L1, C8, L3, and the two 15 pF trimmer capacitors across the collectors and emitters of both transistors. Other NPN transistors like BC54, 2N3642, 43, etc should also work. The circuit is designed for simplicity, so No Audio .... -
The transformer is a 220V to 12V, 50Hz and 3. 6VA PCB type transformer. The model seen in the photo is HRDiemen E3814056. Since it is encapsulated, the transformer is isolated from the external effects. A 250V 400mA glass fuse is used to protect the circuit.... -
This is a fun and useful circuit for demonstrating high frequency high voltge. It can produce up to about 30KV, depending on the transformer used. It is cheap and easy to make, thanks to the standard TV flyback transformer used. It can power LASERS (although.... -
The medical ultrasonic atomizer circuit is composed of power supply circuit, atomization amount liquid level detection control circuit, ultrasonic oscillator and fan motor M, it is shown in the figure 9-111. The power supply circuit is made of timer Q, fuses.... -
The thermostat circuit built to control a 1300 watt space heater which are controlled with a small pulse transformer. Component: LM339 IC, .... -
This circuit used to come as a kit from a surplus supplier, but probably isn`t available anymore. It shows a few novel concepts such as using a 555 as a pulse width modulator (PWM), and series/parallel camera flash transformers. WARNING: This circuit is.... -
Adding negative feedback to an amplifier, especially a vacuum tube amp is not as easy as it may seem. What is there to it Just connect a resistor from the secondary of the output transformer back to the cathode of the pre phase inverter tube. Right Not so.... -
The complete circuit diagram is shown in Fig. 1. Heart of the system is lC2, National`s MM5402 clock chip. It is an MOS monolithic large scale integrated circuit. It`s pin configuration is shown in Fig. 2. The supply is derived from the mains through a.... -
Although this may be a basic question but I`m still struggling with it. In this schematic, two zener diodes D1 and D2 are connected back-to back across relay coil L1. The BVds = -30V for Q1. Can I use 15V(Vz = 15V) zeners for D1 and D2 instead of 5. 1 V.... -
This instructable will show you how to make an audio modulated plasma speaker using a flyback transformer out of an old CRT display, and the all time.... -
In the NIXIE clocks that I have built, I did not want to have the big and ugly mains transformer in the actual clock itself. Instead I use an AC adapter that fits into the mains wall plug. This means that I have to use some sort of an up-converter to.... -
The project Thor was started at the High Voltage Institute of HUT (Helsinki University of Technology) on January 1999. Dr. Martti Aro is in charge of project supervision and Marco Denicolai of project development and implementation. Within this project a.... -
This is a DC to AC inverter using 555 timer and a transformer that is 9-0-9V/230V and rated at 36VA. Component: 555 IC, TIP42C and TIP41C .... -
The medical ultrasonic atomizer circuit is composed of power supply circuit, ultrasonic oscillator and atomizer circuit, it is shown in the figure 9-110. The power supply circuit is made of timer Q, fuse FU, current transformer T, bridge rectifiers UR,.... -
This circuit is a modified hartley oscillator with a couple of extra components included. The transformer is a small audio transformer, type LT700. The primary is center tapped with an impedance of 1Kohms at 1KHz. The secondary has an impedance of 8 ohms..... -
This is an efficient flyback driver for modern cylindrical rectified television flybacks. Many sites doesn`t provide circuits driving these transformers, they simply say that they are bad. I don`t agree. In fact I built this circuit. I spent a lot of time.... -
This circuit is a simple buzzer circuit and it called novel buzzer. It only uses a relay in series with a small audio transformer and speaker. The relay will... -
When I was designing an off-line boost-mode switching power supply, I wanted to model the power transformer, to be able to also simulate the inrush current and other startup behavior. After doing some searches and asking some questions in discussion groups.... -
Back cover removed showing the power supplies upper deck and the original Dayton 2C915A (220vac - 140cfm blower) mounted to the underside of the cabinet. The RF deck enclosure was removed. Upper deck of the power supply with the original blower removed. From.... -
There is a lot you need to know to completely design an inverter. Unless you can acquire a custom made transformer your circuit design is ruled by th.... -
An increasing number of appliances draw a very small current from the power supply. If you need to design a mains powered device, you could generally choose between a linear and a switch-mode power supply. However, what if the appliance`s total power.... -
A stereo valve phono pre built for me by a techie mate. He has the power transformer and all components needed besides the valves which he advised me to source myself based on what would be most suitable to my needs. So, all you experienced DIYers, if you.... -
This power supply was designed for use with the ˜Simple hybrid amp published elsewhere in this issue. It is of course suitable for use in other applications as well. We ve used a cascade generator for the 170 V, a switch mode supply for the 16 V, a series.... -
Voltage is transformed by the transformer turns ratio N2/N1. For instance if 20VAC secondary voltage is required with 120VAC input, a 6:1 ratio would be needed. When full load current is drawn from the secondary winding, the voltage may drop from 5 to 25%,.... -
This power inverter circuit will provide a very stable Square Wave Output Voltage. Frequency of operation is determined by a pot and is normally set to 60 Hz. Various off the shelf transformers can be used. Or Custom wind your own for best results..... -
