Specific embodiment one
[0030] Such as figure 1 The three-phase three-level LLC resonant converter shown is a typical three-phase three-level LLC resonant converter. It includes voltage dividing capacitors, inverters, clamp circuits, resonance circuits, three-phase transformers, rectifier circuits, and filter circuits.
[0031] The voltage divider capacitor is two identical polar capacitors C1 and C2. The positive pole of the polar capacitor C1 is connected to the positive pole of the input voltage source Vin, and the negative pole of the polar capacitor C1 and the positive pole of the polar capacitor C2 are connected as the midpoint of the voltage divider capacitor. , The negative electrode of the polar capacitor C2 is connected to the negative electrode of the input voltage source Vin, and the input voltage source Vin is equally divided into two voltage sources whose voltage is only half.
[0032] The inverter is composed of three three-level bridge arms in parallel to invert t...

Specific embodiment two
[0076] Such as figure 2 The three-phase three-level LLC resonant converter shown is a modified three-phase three-level LLC resonant converter. It also includes voltage divider capacitors, inverters, clamp circuits, resonance circuits, three-phase transformers, rectifier circuits, and filter circuits. The difference from the first embodiment is that the Y-shaped connection point of the primary winding of the three-phase transformer is connected to the midpoint of the voltage dividing capacitor.
[0077] This second embodiment has basically the same beneficial effects as the first embodiment.
