It’s nothing but a AC to DC converter. Keywords: 5V DC power supply‚ rectifier‚ diode‚ filter‚ capacitor‚ zener diode‚ voltage regulator‚ signal‚ waveshape. 1. Introduction I’m designing a 5V DC power supply. Here I’m basically designing a AC to DC converter. To convert the AC to DC‚ I’m using components like full wave bridge rectifier‚ filter & a voltage regulator. To get the constant 5V I use 1N4733A zener diode. The block diagram of this project is given below and giving the part to part

Semiconductor The diode – A diode is an electronic component which allows electric current to glow in only one direction. Diodes are constructed from semiconductors. The anode is the positive terminal and the cathode the negative terminal. LED= light emitting diode a diode which emits light. Semiconductor materials Silicon is the most commonly used semiconductor in electronics‚ germanium is also used. These elements form a stable crystal lattice‚ with each atom sharing its four outer electrons

Oscillator Basics and Low-Noise Techniques for Microwave Oscillators and VCOs Ulrich L. Rohde∗ (ulr@synergymwave.com) Chairman‚ Synergy Microwave Corporation GaAs 2000 – Paris‚ France 2-6 October 2000 Abstract Microwave oscillator design is based on the principle of generating a negative resistance to compensate for the losses of the resonator. Several circuit combinations‚ including one- and twoport oscillators‚ are possible. In this discussion‚ we will first evaluate the conditions of oscillation

Resistor R10 and capacitor C7 connected to pin 4 of IC2 prevent false triggering when IC1 provides the supply voltage to IC2 at first clap. indicates activation of relay RL1 and on/off status of the appliance. A free-wheeling diode (D1) prevents damage of T2 when relay de-energises. This circuit costs around Rs 80

When a circuit is driven with direct current (DC)‚ there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angles. LED - A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright‚ but in most LEDs it

ABSTRACT Flood is one of the disastrous phenomena that caused a lot of deaths to some other uninformed area in the province. The researchers from Negros Occidental High School proposed a study with the objective to construct and develop a flood detection device‚ present a practical device‚ and introduce the device to a certain residents in the province that needs to be aware of flood. After the device was constructed‚ the researchers tested the device in a cup of water. During the testing of device
