Relay Toggle Switch
A relay circuit functions as a double-pole double-throw (DPDT) toggle, controlled by a momentary switch. The design emphasizes simplicity with minimal integration of components such as 555 timers or transistors. The circuit is depicted in an active state. Half of...
Relay protection circuit
Operating power protection devices can be categorized into two types: DC power supply operation and AC operation. AC operating power is favored due to its lower investment costs, simpler operation, and reliable secondary circuit maintenance, making it widely used in...
Lights-On Reminder Circuit
A relay and two diodes are all that is needed; the relay performs the job of a buzzer, so no annunciator is required. When the lights are left on while the ignition is off, the normally closed relay contacts are...
HIGH VOLTAGE NEGATIVE ION GENERATOR
A modified black and white television flyback transformer is utilized in this circuit alongside a voltage multiplier to generate a negative voltage ranging from 9 kV to 14 kV. This high voltage is connected to a discharge needle to create...
Relay Output Proximity Sensor
Q1 is used as an oscillator operating at approximately 300 kHz. Resistor R9 is configured to allow the oscillator to initiate its operation. An object near the antenna will load the circuit, causing the oscillations to cease. This change is...
HV REGULATOR WITH FOLDBACK CURRENT LIMITING
A TMOS MTM7N45 (Q2) functions as a series pass element in a linear high voltage supply that accepts +275 V unregulated input and produces a regulated output of 250 V, incorporating foldback current limiting. A 15 V zener diode, D1,...
PC SMPS PWM chip CG8010DX16
This document contains the datasheet and the circuit diagram of a PC Switching Power Supply utilizing the IC CG8010DX16.
The CG8010DX16 is a highly integrated switching power supply controller designed for use in personal computer power supplies. It features a range...
High voltage power supply
Each subsequent stage adds 1700 volts, resulting in more than 20 kV with 12 stages. However, this voltage can only be achieved when the output of the cascade is unloaded.
The described circuit appears to be a high-voltage cascade generator, commonly...
Features and Power Control Circuit
The most challenging aspect of the build was to find or design a circuit capable of handling the load while remaining within budget. This circuit achieves both objectives. It adjusts the power output using a potentiometer (variable resistor) R1, which...
