2. Wireless Power Transfer in 3D Space

Wireless power transfer means transmitting the electrical energy without using the wires. Certain areas dealing   with explosives or hazardous material, it is advisable  to use the wireless power transfer method for their electrical power requirement. It works on the principle of the high frequency mutual coupling between the two inductive coils. The fields generated by these coils can be tuned to resonance frequency to increase the coupling between these coils. Tuned magnetic field generated by the primary coil is arranged in the vicinity of the matched secondary coil within  a considerable distance.

The main objective of this project is to develop a system of wireless power transfer in 3D space. It consists of two electromagnetic coils, primary and secondary. The AC supply fed from the supply mains at a fundamental frequency is rectified and again made to AC at a different frequency which is fed to another high frequency transformer. This output is then fed to a resonating coil acting as primary of another air core transformer.

The output from the secondary coil of this air core transformer is given to a lamp that glows at considerable distance from the primary coil. The blub continues to glow brightly in the vicinity of primary coil even with the movement of this secondary coil over a 3D space.

4. Ultra Fast Acting Electronic Circuit Breaker

With the use of conventional circuit breakers based on the thermal tripping mechanism  gives a slow response to the overload since these depend upon the time duration of the over load. The concept of electronic circuit breaker overcomes the difficulties by use of current sensing in contrast to thermal based circuit breakers.

Block Diagram

This project is achieved by comparing the load current with a pre fixed rated value. The voltage at the load side sensed by resistor is rectified to the DC. This DC voltage is compared with the preset voltage which is proportional to the rated current value. Logic signals from this comparator circuit drives the MOSFET and the relay.

Load or lamps are connected to the AC power mains through contacts of the relay and coil of the relay is excited by this MOSFET. So when the load increases, lamp gets out of this circuit with this arrangement. Also micro controller receives these signals while relay is operating and accordingly it displays the information on LCD.

5. Automatic Irrigation System on Sensing Soil Moisture Content

Automatic irrigation system reduces the effort of the farmers in regular switching of the pumps to pour out the water to the fields by observing the condition of the soil. The sensing of the soil moisture content is based on the closed path of current flow in the motor circuit. If the soil is wet current starts flows in the motor and while it is dry it offers high impedance to the current flow so the motor stops.

In this circuit, logic signals from the comparator circuit are transferred to the micro controller. Micro controller drives the transistor which is used to excite the relay coil and also sends the signals to the LCD display. As the two terminals which are placed in the soil of the earth forms closed path, result the voltage variation across the comparator.

By receiving this high logic signal from the comparator, micro controller biases the transistor. This transistor excites the relay coil which turns the current to pass through the load by closing the contacts of the relay. The information of the soil and pump conditions also displayed on the LCD display by the micro controller.

6. Cyclo Converter using Thyristors

Cyclo converter is an AC-AC converter which changes the frequency from one level to the other. These may be single or three phase converters based on the load or motor employed. Frequency control to get the variable speed of induction motor gives the better performance than using only voltage control by AC regulator circuit. This circuit is implemented to get  speeds at three different frequencies i.e., the fundamental (F), half (F/2) and one third (F/3) frequencies.

Dual bridge SCR connected across the induction motor consists of eight SCR’s as two bridges, positive and negative and these thyristors are driven by the Opto-isolators. Microcontroller receives the input signals from the two slide switches to select the particular step of the speed out of the three steps. Triggering pulses so generated by the microcontroller as per the program written, drives the Opto – isolator and further respective SCR to get turned ON based on pulse triggering. Induction motor speed is varied according to the switching of these thyristors by delivering lower frequencies of F/2 and F/3.

10. Long Range FM Transmitter with Audio modulation

Frequency modulation refers to modulating the frequency of the carrier signal with the signal to be transmitted. It must be less prone to interference with other communicating signals and requires bandwidth which is twice the sum of the modulating signal frequency and the frequency deviation. This project develops a low cost long range FM Transmitter with audio modulation.

Block Diagram by Edgefx Kits
Block Diagram

The FM transmitter has three RF stages as variable frequency Oscillator (VFO), a class C driver stage and a class C final power amplifier. The audio signal output from the microphone is used to modulate the frequency output of oscillator. In the output we have used a stick antenna for short distance transmission. To check the output of the transmitter, initially, the first preset is adjusted.

The frequency is adjusted to a range where no commercial transmission takes place. Then the FM receiver on the mobile phone is set to the search mode so as to get this signal. Once we give a gentle tap on the microphone, the sound can be heard on the mobile phone in  FM band. In case we want to use the Yagi Uda antenna, the second preset or the trimmer can be adjust to set the impedance for the distance range selection.
