Rancang Bangun Inkubator Skala Laboratorium dengan Sistem Pemanas Induksi (Induction Heating) Berbasis Mikrokontroller Atmega 8535

Abstract

In general, incubator works using heating elements made of plate, where a large electrical power consumption especially when heated first takes quite a long time until the tool can be operated. In addition, to consider also the temperature uniformity inside the pattern by observing the placement of the heating element. The use of incubators that needs to be calibrated before being used again and it is also one of the problems keteledoran users. Induction heating method was chosen because it has a controlled heat supply levels and the rapid warming time. The use of induction currents that arise on the workpiece (incubator) to make its components relative increase in temperature does not occur, so that life becomes more durable and does not require an expensive component. As for the operation of incubator this induction method does automatics and her treatment is also very easy. Induction heater consists of 3 main circuit power supply circuit with the power of 240 Watts, the driver sets the current generation AC and AC generator circuit is set automatically by the system microcontroller Atmega 8535. The process of transferring the heat from this testing utilizing heat transfer by convection from the wall material incubator. From the test results that were obtained within 500 seconds, induction heating systems capable of raising the temperature of the incubator is 99, 6 0C.
