Abstract:

This paper presents the results of the research, calculation and manufacture of a single-phase inverter with an intermediate stage at high frequency, to control a grid-connected single-phase DC/AC converter as required by the load demand regulation program. This converter overcomes the shortcomings of traditional inverters. The use of a high frequency transformer provides better separation between stages, and the output frequency can be customized through the control of input pulses. This control structure consists of a current control loop on the inner ring and a power control loop on the outer ring. According to this structure, the internal loop controller uses a resonant controller with parameters defined in the frequency domain and controller. This paper constructs a control structure for controlling a grid-coupled single-phase DC / AC converter capable of operating as required by a load demand regulation program. The research results show that the instantaneous power characteristic curve at the output of the DC/AC converter always follows exactly the set power characteristic curve. At the same time, the voltage characteristics and current calculation at the output of DC/AC converters are always standard sinusoidal form to ensure the IEEE519 power quality standard, applied in the field of industrial control.
