Mains 220 V AC Line Filter Circuit for Transient Suppression
The 220 V mains AC line filter circuit described here has two functions: it prevents high-frequency waves from being sent back into the power network and it protects connected equipment from power line disturbances and surges. This circuit employs a number of components, such as capacitors, resistors, inductors, and a varistor, which are deliberately positioned […]
Convert any Existing AC Lamp into Timer Controlled Lamp
The proposed push button timer circuit module can be directly integrated with any existing switch contacts of a lamp and enable the lamp to be converted into a timer controlled lamp. A common problem arises whenever one wants to replace a mains AC lamp controlled by a switch with a timer or a time switch. […]
AC 220V Over Current Monitor and Cut OFF Circuit
The proposed AC mains 220 V load over current cut off circuit continuously monitors the current flowing through a connected load. If this current increases beyond a certain preset level, the circuit trips the relay and disconnects the load from the AC. Basic Working This 220 V over current cut off circuit is indeed subject […]
Mains AC Current Detector Switch Circuit
The circuit I have I have explained in this article allows one to detect the current consumed by a device and to power one or more other devices accordingly. Indeed, the solution of a switchboard is not always applicable because it is often not very practical. Furthermore, some devices such as computers only start when […]
Understanding AC Circuit and Calculating AC Waveform
The sinusoidal waveform or sine wave is the most commonly used AC waveform in circuit theory. When a periodic AC waveform is produced by a voltage source, it creates an EMF that changes polarity at regular intervals, with the time it takes to complete one full reversal known as the waveform’s period. Direct current, also […]
