Abstract:Zaradi vse bolj sofisticiranih krmilnih enot in elektronskih sklopov naprav je potrebna vedno večja pozornost z namenom, da se zagotovi delovanje naprave v skladu z Direktivo o elektromagnetni združljivosti. Tako mora vsaka naprava dosegati mejne vrednosti preizkusov odpornosti in oddajanja motenj, ki so glede na vrsto naprave določene v produktnih standardih za elektromagnetno združljivost. Diplomsko delo zajema enega izmed številnih preizkusov odpornosti, ki so določeni v produktnem standardu in jih mora naprava, kot je grelnik sanitarne vode, prestati. Med preliminarnim preizkusom odpornosti na elektrostatično razelektritev pri grelniku sanitarne vode s krmilno enoto ET4 je bilo ugotovljeno, da le-ta ne dosega pogojev standarda. Zato je bilo potrebno povečati odpornost na elektrostatično razelektritev. Med naborom rešitev je bila najprimernejša tista, ki vključuje supresorske diode. Zaradi teh je bila potrebna tudi sprememba tiskanega vezja krmilne enote. Rešitev je bila uspešno implementirana in se kot taka uporablja v proizvodnji krmilnih enot in v proizvodnji grelnikov sanitarne vode.

Title:ELECTROSTATIC DISCHARGE IMMUNITY OF WATER HEATER
Abstract:Due to more and more sophisticated control units and electronic assemblies of different devices, greater attention is required in order to assure the operation of the device in accordance with the EMC Directive. Thus, each device shall comply with the limit values of immunity and emissions testing, which, according to the type of device, are specified in the product standards for electromagnetic compatibility. This graduation thesis deals with one of the many immunity tests which are specified in the product standard and which a device, such as sanitary water heater, shall undergo. During preliminary testing of water heater equipped with the control unit ET4 to immunity to electrostatic discharge, it was found out that it does not meet the requirements of the standard. Therefore it was necessary to increase the immunity to electrostatic discharge. Among the range of possible solutions the one including suppressor diodes was the most appropriate. Because of this it was also necessary to modify the printed circuit of the control unit. The mentioned solution has been successfully implemented and as such it is used in the production of control units and in the production of sanitary water heaters.
Keywords:directive, electromagnetic compatibility, electrostatic discharge, standard, water heater
