Simple Power Supply Circuit easy to make Schematic Diagram

Initially, voltage from AC 220V or 110V enters the transformer, which reduces it to 12V AC. This AC voltage is then rectified using either four diodes or a bridge rectifier to convert it to DC voltage. The resulting DC voltage...

pulse width modulated (PWM) controller for high current

The second 555 timer was configured as a monostable circuit, commonly referred to as a one-shot since an output pulse only occurs if there is a trigger on the input. When this timer is triggered, the potentiometer in the RC...

How to amplify a square wave cheaply

A piezo disk is being driven at a frequency of 100 Hz or lower, with the output from the signal generator limited to 10 V. The goal is to amplify this output to 50 or even 100 Volts. To achieve the...

Speed controller circuit change please help

To create a PWM controller, begin with a sawtooth generator powered by a 7.5V regulated supply to achieve a Vpp of 5V. Connect the sawtooth output to one input of a comparator and the MAP voltage to the other input...

H Bridge Direct Current Motor Control Circuits

This page features H-Bridge circuits used for controlling direct current motors. Several designs are shown using both CMOS and Bi-Polar power devices. These circuits could be used as the basis for Model Railroad DCC Boosters or PWM motor controllers. The...

Versatile Multifunction Circuit Uses Only Three Inverters

The versatile circuit can be employed to achieve various functions, including an astable multivibrator, a monostable multivibrator, a switch debouncer, or a frequency discriminator. Inverters U1a and U1b are configured as a latch. When the input voltage (VIN) is high,...

12 vdc to 240 vac inverter

This 12 VDC to 240 VAC inverter circuit does not utilize specialized components, such as the toroidal transformer commonly found in many inverter circuits. The inverter circuit described is designed to convert a 12 VDC input into a 240 VAC output...

PWM Control Dimming Halogen Lamp

The PWM control dimming circuit for a halogen lamp is illustrated. The halogen lamp operates at a rated voltage of 12V with a nominal power of 20W. This dimmer circuit is capable of adjusting the intensity of the halogen lamp...

Digital Sine Wave Oscillator

If found myself in need of a 1 KHz signal source for an experiments. My function/sweep generator was needed as a pulse generator for the same experiment, so I went though my junk box, looking for circuits from long ago...
