Second-Order Harmonic Current Propagation Characteristics in Two-Stage Inverter Based on Virtual Impedance

Second-Order Harmonic Current Propagation Characteristics in Two-Stage Inverter Based on Virtual Impedance

The instantaneous output power of a two-stage single-phase inverter pulsates at twice the output voltage frequency, generating second harmonic current(SHC) in the front-end dc-dc converter. The optimization of loop control of the front-end dc-dc converter is an effective and costless method for this...
