novel shema for dc converter

Sažetak
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 circuit . These switched mode circuits generate voltage/current shapes which generate the required first, but also the higher, parasitic, harmonics which can influence the ac loads. One of the main designing problem of the inverter circuits is the higher harmonics rejection which can be obtained by output filters, pwm control strategy or by the 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. The main feature of this method is that it ensures simple and very satisfactory higher harmonics rejection with only a few injected pulses per period. The harmonic analysis of the several examples is presented, as well as the proposed solutions for the realisation of the inverter circuit.
