| Abstract | A pulse width modulated (PWM) inverter without expressed carrier frequency generator represents a nonlinear oscillating feedback circuit in which rise the selfoscillations. Such inverter can be characterized as a two level controlled system. The present paper deals with the description of the operation, method of analyse and achieved results at the such inverter type in case of a passive resistance load. The matter of the analysis is to derive the common valid equations among the part circuit values, external voltages, load and electrical inverter parameters to gain the basis for the optimal synthesis of the output LC filters.The following method was employed: - The analytic expressions were derived for the voltage and current responses in the steady-state operation. - The analysis of the derived expressions was performed. - The graphical dependences suitable for the synthesis of the optimal LC filters and working areas of inverters were gained by calculating of the analytic expressions. |
