A DC motor PWM speed control circuit
Most governors utilize pulse width modulation (PWM) and pulse position modulation (PPM) in their circuits. The 555 timer is commonly used in these applications. The pulse width is typically fixed at 0.5 milliseconds, which is essential for the functioning of...
Schematics power supply switching PCB
The switching power supply provides 12 volts at a maximum of 10 amps, utilizing a discrete transistor regulator with an operational amplifier acting as a comparator in the feedback circuit. The schematic does not depict the front panel power-on indicator....
Pulse Width Modulation DC Motor Control
Often, people attempt to control DC motors with a variable resistor or variable resistor connected to a transistor. While the latter approach works well, it generates heat and hence wastes power. This simple pulse width modulation DC motor control eliminates...
Design and making of the stabilized voltage supply of switch
Under the loading condition of the resistance, the output voltage (Uo) variable range is from 30V to 36V, with a maximum output current (Imax) of 2A. When the input voltage (U2) changes from 15V to 21V, the voltage regulation factor...
Radio Buttons Using Push On Switch Latching Circuit
This is a switching circuit that provides a latching mechanism to create a set of radio buttons using push buttons. This circuit consists of an interlocking circuit.
The switching circuit operates on the principle of latching, allowing multiple push buttons to...
Structural analysis of switching power supply
A daily switching power supply primarily provides direct current (DC) power to electronic devices. The required DC voltage for electronic devices typically ranges from several volts to over ten volts, while the input voltage from the mains supply is either...
About a PWM power inverter
A few months ago, a search was conducted for an easy-to-build PWM inverter that does not require any PIC programming. The investigation led to a consideration of a 555 PWM amplifier circuit.
The 555 timer IC is widely used in various...
PWM inverter circuit based on SG3524 : 12V input 220V output 250W
A simple PWM inverter circuit utilizes the SG3524 integrated circuit. This PWM inverter is designed for a 12V input, providing a 220V output with a maximum output power of 250 watts. The output power can be extended further.
The described PWM...
Car Large capacitor charge controllers
One-farad capacitors require some care. It's common knowledge that they must be pre-charged with a current-limiting resistor before plugging in. It is less common knowledge that those fifty-dollar smart cap controllers are in fact very simple devices, two dollars for...
