Induction heating is a non-contact heating process. Using high-frequency electricity to heat the electrically conductive material. Because of this non-contactprocess has the advantage of not polluting the environment. It is also very efficient because the heat generated in the workpiece. Can be compared with other heating methods where heat is generated in the flame or heating element, which then heats the workpiece. Because of these reasons reinforce the unique induction heating for several applications in industry. Design of control system for high frequency induction heating on conductive workpiece heating systems are systems that are specifically designed for induction heating for every application that aims to heat the conductive material or workpiece in a clean, efficient and controlled manner.

ABSTRACTMagnetic induction system has been developed using 12 receiving and transmitting coils. The excitation of the sine signal from the transmitting coil causes a change of magnetic field and electric field at a certain time interval in this study using a sine signal with a frequency of 2 MHz , the change causes the induction emf on the receiving coil. The amount of induced emf is also influenced by the permeability of the medium between the transmitting and receiving coil. The induction on the receiving coil will be acquired by the MIT system and its image reconstruction is made. The MIT system in this study is also a development of the MIT system from previous studies using 8 coils. The result of this research succeeded in getting 2D image reconstruction which already resembles the actual object shape but not yet perfect. The MIT system has been made using 12 coils with an average inner resistance of 7 , 100 winding, and 4 cm coil length. The distance between the face coils is 12 cm and the coils are arranged in a circle. The metal objects used in this study are empty iron cylinders and square iron."

"Transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage. Transformers act through electromagnetic induction; current in the primary coil induces current in the secondary coil. The use of transformers includes reducing the line voltage to operate low-voltage devices (doorbells or toy electric trains) and raising the voltage from electric generators so that electric power can be transmitted over long distances.Power electronics is a rapidly growing technology encompassing a large variety of applications including automotive, telecommunications, computers and alternative energy system. Traditionally, transformer design has been based on voltage and current operating in low frequency. In switching circuit (SMPS) transformer works at high frequencies which led to considerable reductions in the size of magnetic component. The type of signals to be transferred from the primary to secondary windings dictate the type of transformer that most suitable to the application. Operation of a transformer at higher frequencies will lead reduced magnetizing inductance compared to lower frequencies.This project is aimed to analyse and design a transformer purposed for high frequency uses. The expected outcomes of this project are defining the design factor of a high frequency inductors and transformers. Modelling and simulation of the transformer will be performed as part of this project, along with design approach and design factor."

"Dalam skripsi ini high gain dualband quadrature down conversion mixer dirancang dan disimulasikan menggunakan perangkat lunak Advance Design System (ADS). Pada sistem transceiver, mixer berfungsi sebagai pentranslasi frekuensi dari frekuensi sinyal baseband ke frekuensi sinyal pembawa, maupun sebaliknya. Dalam perancangan mixer, permasalahan yang sering muncul adalah keberadaan frekuensi image yang dapat menghasilkan keluaran yang tidak diinginkan. Quadrature mixer adalah salah satu solusinya. Perancangan mixer yang dilakukan ditujukan untuk bekerja pada frekuensi 900 dan 2300 MHz. Pada perancangan mixer ini digunakan topologi Gilbert cell dengan konfigurasi common emitter pada transconductance untuk memperoleh conversion gain yang tinggi. Selain itu, quadrature coupler digunakan untuk menekan frekuensi image pada frekuensi keluarannya. Hasil simulasi pada frekuensi 900 dan 2300 MHz didapatkan masing-masing nilai return loss -18,2 dB dan -19,8 dB, coversion gain 36 dB dan 26 dB, noise figure DSB 17,69 dB dan 22,33dB, noise figure SSB 18,69 dB dan 31,80 dB, serta IIP3 19,99 dBm dan 3,52 dBm, dan isolasi antar terminal sebesar < -300 dB. Mixer yang dirancang mengonsumsi daya sebesar 39,8 mW. Setelah dilakukan pengukuran, terjadi pergeseran frekuensi kerja pada frekuensi 900 dan 2300 MHz masing-masing sebesar 113 MHz dan 475 MHz, isolasi antar terminal < -30 dB.

In this bachelor thesis, high gain dualband quadrature down conversion mixer is designed and simulated using Advanced Design System (ADS) software. In a transceiver system, mixer serves as frequency translator of the baseband signal frequency to the carrier signal frequency, or vice versa. In the mixer design, the problem that often appear is the existence of image frequency that can produce unwanted output. Quadrature mixer is one of the solution. The design of the mixer was intended to work at frequency of 900 and 2300 MHz. The mixer design used Gilbert cell topology with common emitter configuration on the transconductance to obtain high conversion gain. Furthermore, quadrature coupler is used to suppress the image frequency at the output. The mixer simulation result at frequency of 900 MHz and 2300 MHz respectively shows return loss -18,2 dB and -19,8 dB, coversion gain 36 dB and 26 dB, noise figure DSB 17,69 dB and 22,33dB, noise figure SSB 18,69 dB and 31,80 dB, IIP3 19,99 dBm and 3,52 dBm, and port isolation for both frequencies < -300 dB. The mixer consume power of 39,8 mW. After the measurement, there are operating frequency shifting in the 900 and 2300 MHz respectively 113 MHz and 475 MHz, isolation between terminals <-30 dB."
