Design and implementation of 2kHz inverter for induction hardening machine Thida Aung Zaw Min Naing Induction hardening machine is to change the structure of chemical and physical properties of materials, usually metals, in order to improve their properties in relation to a particular application. This machine is based on the high frequency induction heating, electrical and electronic technologies. The use of electronic controls in induction hardening machine is a new area industrial electronics. From the electronic point of view, induction hardening machines lire composed of rectifier, inverter and protection system. In this project, SCRs are selected as electronic switching devices for inverter circuits. By controlling the SCR s, the desired high frequency and power to harden the materials can be obtained. This paper concentrates on designing and implementing of medium frequency inverter circuit for induction hardening machine aiming to be a good local product considerably comparable with foreign counter-parts in terms of cost. Design has been approached by surveying the induction hardening machines installed at No.4 Farm machinery industry, Kyaikkalo in Yangon and theoretical concepts lire described in detail in this paper. 2009 http://hdl.handle.net/20.500.12678/0000002476 https://meral.edu.mm/records/2476
