AbstrakNowadays induction heating has become one of the people's choices in the heating process both in industry and households. Induction heating technology is also growing. But the electrical quantities that change with the temperature changes in the induction heating process must also be analyzed. To make induction heating, we need a device that is capable of producing large electrical energy. This tool uses a 12 Volt DC voltage, strong current 10 ampere and with a 120 watt input power. This induction heater is made using a half bridge inverter which generates heat through waves at high frequencies. The resonant frequency used is 25kHz. From the test obtained an average temperature increase of 134.5 ° C at the 600th second with a paper clip load and with a voltage of 3.33 Volts, a current of 0.15 A, a power of 0.56 watts, and a heat of 19.5J, and a test with a load nails obtained an average temperature of 136 ° C at 360 seconds with a voltage of 4.54 V, a current of 0.27 A, power of 1.12 watts, and a heat of 33.6JKata kunci : Pemanas Induksi, frekuensi, suhu, Solenoide.

Induction hardening is an important manufacturing process to control the mechanical properties of metal parts where surface hardness is enhanced while the core retains the toughness. This paper presents the modeling and simulation of the induction hardening processes with the finite element analysis. A coupled electromagnetic-thermal analysis is applied to the induction heating process. The temperature distributions in parts are obtained in heating and quenching process. The induction heating and quenching are highly nonlinear processes because the materials properties of the parts are temperature dependent. The final hardening process involves the determination of martensite volume content and hardness value. An algorithm is utilized to determine the volume fraction of diffusion controlled metal phase transformation and martensite content. Finally, the hardness value is converted from martensite content. Results for a complex surface hardening are presented. The effects of input power, frequency and air gap on final hardened pattern are systematically studied.

Abstract - Automatic system have grown widespread across all sector so do water heater. Traditionally, heating water is done by utilizing fire as heat source. As the growing of technology, the heating process could be done by manipulating electrical energy by convert it to heat. Electrical energy is flown to a metal rod that contact directly with the water which increase the water temperature. On some case, appropiate water temperature is needed. Altough, a thermometer is needed to read the actual temperature as a feedback value for the system and a system that can control the electricity current flow through the heater that the heat produced is linear to the current flow. With implementing microcontroller as a process node for generating PWM signal, this problem can be solved. Also, Labview is needed as an interface for monitoring and bursting an output which have been processed by Proportional, Integral, and Devivative (PID) controller to producing accurate and stable heat. Based on the results of testing, the system is able to provide a rapid response to any changes that occur, both changes in set-point and changes in water temperature (actual value). Another test is done by comparing the temperature value detected by the temperature sensor in this device with an external digital thermometer placed in the same place, and from some of the tests the temperature value detected by the temperature sensor in this device has a difference of ± 0.19 ℃ with a digital thermometer.

Abstract This study focuses on two major advantages of induction heating over flame heating in the treatment of coated boiler tubes. In both cases the induction heating process is simple, fast and effective. Firstly, we will show how the the use of induction heating results in exceptionally thick and hard coatings with low porosity. Having high corrosion and wear resistant properties, the products can satisfy industry's needs for reliable coatings with a long service life. Next, the study will detail how a pipe with the coating already applied can be simultaneously bent by induction heating while the coating is melted and fused to the pipe. The result is a thicker, more even and reliable coating than that accomplished by the flame sprayed method on a bent pipe. The process is not only less cumbersome, but again provides a superior product for the market.

Energy saving can be maximized by rectifying the intermediate conversion processes involved during the utilization of solar energy. The system eliminates the transformation of electrical form of solar energy into another form by directly utilizing its electrical energy in the management and control of power supplies obtained from renewable (solar) and conventional (mains) energy sources. A current control scheme is presented in which current delivered by solar supply is used to control the current in mains supply in such a way that both currents are inversely proportional to each other. Any increment in solar current opposes mains current in the same proportion and vice versa. A balanced common physical output is resulted from the electrical load supplied by each source separately. A natural variation in solar radiation is utilized to fluctuate the solar current which is further used to change the mains current. Energy saving is maximized in this supply management by the optimal utilization of solar energy.
