Voltage regulator for projection lamp
The circuit regulates the RMS output voltage across a load, specifically a projection lamp, to 100 volts ±2% for input voltages ranging from 105 to 250 volts AC. This regulation is achieved by indirectly sensing the light output of lamp...
High Voltage Dc Generator Circuit
In the miniature high-voltage DC generator, the circuit receives input from a 12 V DC power supply, which is amplified to produce a 10,000 V DC output. This process induces a pulsating signal of opposite polarity in the secondary winding...
Charging a low-voltage high-C capacitor. Efficiently
The first option is a Zener diode. There are several 2.2V Zener diodes available that could adequately protect the capacitor. However, a significant drawback is that half the energy may be wasted across the diode short. The question arises whether...
Three-phase controlled rectifier circuit
Trigger circuit routing forms include various types such as simple trigger circuits, single-junction transistor trigger circuits, synchronous sine wave trigger circuits, sawtooth transition phase shift (synchronous) trigger circuits, and integrated trigger circuits. This section presents individual cases for introduction due...
Rectifier/filter circuit Semiconductors
A bridge rectifier module is strongly recommended over building a bridge rectifier circuit using individual diodes. These modules are designed to be mounted on a metal heat sink. A metal enclosure is preferred over a plastic one due to its...
12V to 20KV inverter circuit diagram using IC555 STUN GUN
A 12V to 20000V inverter circuit diagram (stun gun) is presented. This circuit generates a very high voltage and must be used with caution to prevent electric shock. The transformer can produce over 1000V and amplify the voltage by eight...
Half-wave rectifier circuit principle
A bridge rectifier capacitor filter serves as a primary power supply for current amplifier circuits. This power supply configuration is straightforward and offers enhanced performance. The bridge rectifier circuit is a full-wave rectifying circuit, meaning it converts both the positive...
15 V FOR VTVM
A simple rectifier circuit replaces the battery in a vacuum-tube voltmeter (VTVM). It provides good regulation and eliminates the need for frequent battery replacement. The battery should be removed before using the supply. The AC source can be the 6.3-V...
Salvaging Interesting Gadgets Components and Subsystems
The high voltage power supply is likely capable of delivering between 12 to 30 kVDC at a current of 1 or 2 mA. This output is suitable for various high voltage applications, including experiments, plasma globes, negative ion and ozone...
