Build an Experimenters Power Supply
The incoming AC is routed to the primary terminals of a 12.6-volt transformer. The hot side of the AC is connected through a fuse and a single-pole single-throw (SPST) toggle switch. When the switch is in the OFF position, the...
Power Supply Schematic
The power transformer features three secondary windings: 720V at 120mA center-tapped for the plate and screen supplies, 6.3V at 3.5A for the tube filament and bias power supply, and 5V at 3A (unused). Since the 5V secondary is not utilized,...
The H-Bridge Circuit Control Design in DC Motor Application
The diagram below illustrates an H-Bridge circuit featuring four inputs and an external power supply. The control application must enable the motor to operate in both forward and reverse directions.
The H-Bridge is a crucial component in motor control applications, allowing...
24v to 12v converter
The 24V to 12V converter schematic is straightforward; however, it is important to ensure that all components, including transistors and integrated circuits, are adequately heat dissipated and electrically insulated from metal surfaces. The schematic diagram is derived from the circuit...
PWM sound Tutorial
This document demonstrates the use of an Arduino PWM output pin to generate sound. The output pin can be toggled rapidly between LOW and HIGH states to create a square wave. If the frequency of this square wave is within...
Simple PWM controller
This 555 timer based PWM controller features almost 0..100% pulse width regulation using R1, while keeping the oscillator frequency relatively stable. The frequency is dependent on values of R1 and C1, values shown will give a frequency range from about...
Circuit diagram of an analog circuit PWM
The image illustrates a circuit that utilizes a linear potentiometer (or linear Hall element) to control the PWM generation for two chassis drive motors in a gamepad or joystick used in model aircraft. J1 represents the handle of the potentiometer,...
H-bridge driver circuit composed by the Smart SIPMOS
The BTS412B functions as two high-side power MOSFET switches, while two BU271L (50V, Zhang 1n) serve as low-side switches, forming a bi-directional H-bridge DC motor drive circuit. This configuration is designed for electrical automatic door systems, capable of handling continuous...
Inductorless 3-5 Volts Converter
By configuring a comparator and a transistor to control the oscillator in a charge pump circuit, it is possible to generate a regulated output of virtually any desired value. Charge pump integrated circuits (ICs) can either invert or double an...
