    The paper presents problems connected with generation of sin – and trapezoidal signals as basic ones in the DC/AC energy conversion process. Questions on loads of various characters while alimented with sine – and trapezoidal voltages have been outlined. Basic construction features of both types microcomputer equipped inverters have been discussed, in particular those dealing with a significant number of safety measures and with characteristic attributes of final power stages, determining the behaviour of inverters in various output power conditions. On examined sample inverter types of own design a complete compliance with requirements of electromagnetic compatibility standards has been pointed out thanks to proper planning and structural solutions.
