On the basis of traditional dual-loop control, an impedance reconstruction control of the source PWM inverter is proposed, which can effectively suppress the high-frequency oscillation of the island power system. The following conclusions can be drawn from this paper:
The high-frequency isolated DC-DC converter is a well-known topology for high-power DC-DC conversion, featuring electrical isolation and transformer capabilities and the ability to change the switching frequency [20, 21].
After adding impedance reconstruction control, the output voltages and currents of the source PWM inverter loaded with pure resistive load remain stable under different output power; when the load is a PWM rectifier, the high-frequency oscillation of the island power system is effectively suppressed.
Ref. proposed a high-frequency isolated dual PWM frequency conversion and speed regulation structure, discussing a new method that combines high-frequency isolation and frequency control and addressing the issue of large volume in traditional frequency converters.
This approach effectively addresses the issues of voltage conversion by itself, excessive space occupation when separated from power frequency transformers (mobile substations), and the use of traditional two-level inverter output stages, which result in high harmonic content and poor waveform quality.
The output stage was an NPC three-level inverter circuit, followed by an LC filter to filter the PWM waves of different frequencies. The IGBTs used were model H20R1203, manufactured by Infineon. The isolation stage employed the DA962D4 drivers and the NPC three-level output stage used the 1EDI60N12AF gate drivers.
