The resonant inverter accepts a dc input voltage, and generates very high frequency (VHF) ac, which is processed through the transformation stage to produce different ac voltage and current levels. The resonant rectifier then converts the trans-formed ac power back to dc.
The working principles of the high-frequency isolated NPC three-level inverter frequency conversion and speed regulation system topology are as follows: The three-phase industrial AC input is converted into a DC power source via a three-phase diode rectifier.
Other limitations of many inverter topologies appropriate to VHF operation include the use of bulk “rf choke” inductors (which is disadvantageous for rapid transient response and on-off control), and a tight tie between device parasitic capaci-tance and achievable output power and frequency , .
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].
