This paper describes the principles of operation and the physical model of an integrated AC-DC rectifier acting as a reverse-conducting transistor AC-DC rectifier with MOSFETs as fast-switches with a low ON-state voltage drop. An integrated AX-DC rectifier, when seen as a transistor AC-DC rectifier, can be used in many fields, e.g., for multi-funct...

... The control systems [9,12] are equipped with diagnostic connectors enabling access to information and diagnostic procedures. The component of the ignition system is considered to be unfit if its operation results in a significant increase of toxic compounds emission from the exhaust system [1,7,[13][14] by 50% in relation to the permissible values for a given type of vehicle. To find out the damage, in addition to the standard procedures for detecting unfit elements, special testers are necessary. ...
The research problem in the article was aimed at assessing the effectiveness of fault recognition for 3 injection systems. Diagnostic tests using the on-board diagnostic system were carried out for the following injection systems: Siemens Simos 2, Rover MEMS 1.6 and Siemens Simtec 56.5. The aim of the research was to record signals from individual sensors and to read error codes for proper operation and simulated damage. The research on the real object was to record the change of the ignition advance angle and its control values during climbing the hill in the first and second gear at a constant speed.
... The article is devoted to issues related to the test systems of the starting circuit. Today's test systems are associated with the analysis of defects that have a direct impact on driving safety and occur mainly in the subsystems of the chassis and bodywork [3,11]. In the case of the starting system, the operation process due to natural wear and tear or damage is not monitored or tested in diagnostic and repair stations. ...
The article is devoted to issues related to the test systems of the starting circuit. The article develops the model and simulation of the wear and tear of starter sleeves by changing the size of the starter armature gap. The analysis of the impact of the starter sleeves condition on the device's power curve was conducted in the Matlab Simulink program. For the model developed in the Matlab Simulink program, resulting from operational wear as a function of the car's course, a method of power characterisation for failure verification was proposed.
