Inverters today are realised with well known converter circuits, as the push-pull, Half bridge, bridge, as well as with the complex stepped and interval variable circuits. One of the main designin problem of the inverter circuits is the higher harmonics rejection which can be obtained by output filters, pwm control strategy or by combination of both. The paper deals with the simple control strategy for the rejection of the higher harmonics which is based on the injection of the control pulses at the strictly defined angles and with proper amplitude. |
