relay triac
The task involves converting a relay in a design to a triac. The circuit switches a 120V nichrome wire with a resistance of 60 ohms. The circuit is powered by a 12V transformer, and there is a 120V neutral and...
Homemade tablet CarPC
The momentary hold relay board and the accessory delay module are components designed for automotive applications. The momentary hold relay board powers the GPS unit and the tablet, eliminating the need for manual button activation. The accessory delay module is...
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...
High voltage switching stabilized voltage supply circuit
A high voltage switching stabilized voltage supply circuit is illustrated in the diagram. This is the switching power supply for an 80P type color television. It utilizes auto-excitation and a PWM circuit. The output is isolated from the power system,...
Low voltage lamp flasher
The circuit consists of a relaxation oscillator created by Q1 and an SCR flip-flop formed by Q2 and Q3. When the supply voltage is applied to the circuit, the timing capacitor C1 charges to the firing point of the Programmable...
13KV High voltage power supply
This high-voltage power supply features an inverter circuit centered around Q1, which generates 150-V pulses for the converter SCR1 and capacitor C2. The output from component ?2 produces a 4.5-kV pulse, which is further amplified by a voltage-tripler network to...
high-voltage-inverter-circuit-diagram.html
This inverter circuit operates using a transistor and transformer, along with other components, to elevate the voltage. The input supply voltage ranges from 3V to 6V DC, which is then converted to a high voltage AC output. However, the output...
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...
HV regulator with foldback current limiting
A TMOS MTM7N45 (Q2) is utilized as a series pass element in a linear high voltage supply that accepts +275 V unregulated and produces 250 V regulated with foldback current limiting. A 15 V zener diode (D1) provides the DC...
