RC Integrator
The RC integrator is a series connected RC network that produces an output signal which corresponds to the mathematical process of integration. For a passive RC integrator circuit, the input is connected to a resistance while the output voltage is taken from across a capacitor being the exact opposite to the RC Differentiator Circuit. The capacitor…

RC Waveforms
RC circuits can produce useful output waveforms such as square, triangular and sawtooth, when a periodic waveform are applied to its input. RC circuits have the ability to produce different output shapes of RC waveforms depending on the type and frequency (period) of signal waveform applied to its input terminals. In the previous RC Charging…

RC Discharging Circuit
When a voltage source is removed from a fully charged RC circuit, the capacitor, C will discharge back through the resistance, R RC discharging circuits use the inherent RC time constant of the resisot-capacitor combination to discharge a cpacitor at an exponential rate of decay. In the previous RC Charging Circuit tutorial, we saw how a Capacitor…

RC Charging Circuit
When a voltage source is applied to an RC circuit, the capacitor, C charges up through the resistance, R The charging of a capacitor is not instant as capacitors have i-v characteristics which depend on time and if a circuit contains both a resistor (R) and a capacitor (C) it will form an RC charging…

Single Phase Rectification
Rectification is the process of linking an AC power supply to a connected DC load by means of solid state semiconductor devices. Rectification converts an oscillating sinusoidal AC voltage source into a constant current DC voltage supply by means of diodes, thyristors, transistors, or converters. This rectifying process can take on many forms with half-wave,…

Solid State Relay
Solid State Relays are semiconductor equivalents of the electromechanical relay and can be used to control electrical loads without the use of moving parts. Unlike standard electro-mechanical relays and contactors which use coils, magnetic fields, springs and a variety of mechanical contacts to control and switch a power supply. The Solid State Relay, or SSR as it is…

Transient Suppression Devices
Transient suppression devices can significantly reduce the amount of energy released as a result of over voltage spikes and surges. We would like to think that the AC or DC power supplies we use to power our circuits are both clean and well-regulated supplies. However, the switching of AC inductive loads or the switching of…

Switch Mode Power Supply
Linear voltage IC regulators have been the basis of power supply designs for many years as they are very good at supplying a continuous fixed voltage output. For a dedicated switch mode power supply, linear voltage regulators are generally much more efficient and easier to use than equivalent voltage regulator circuits made from discrete components…

Unijunction Transistor
The UJT is a three-terminal, semiconductor device which exhibits negative resistance and switching characteristics for use as a relaxation oscillator in phase control applications. The Unijunction Transistor or UJT for short, is another solid state three terminal device that can be used in gate pulse, timing circuits and trigger generator applications to switch and control either thyristors and triac’s…

Diac Tutorial
The Diac is a two-junction bidirectional semiconductor device designed to break down when the AC voltage across it exceeds a certain level passing current in either direction. The Diode AC switch, or Diac for short, is another solid state, three-layer, two-junction semiconductor device but unlike the transistor the Diac has no base connection making it a two terminal device, labelled A1 and A2.…
