Switching circuit apparatus and electronic power converter capable of reducing common mode noise in asymmetric circuit

A power converter apparatus comprising a switching circuit apparatus, the switching circuit apparatus comprising:

• a first port terminal and a second port terminal;
• a first inductor;
• a switching circuit unit including at least one switching element;
• and
• a conductor part,
• wherein the switching circuit unit comprises at least a first terminal and a second terminal, the first terminal being connected to the first port terminal via the first inductor, the second terminal being connected to the second port terminal,
• wherein the switching circuit apparatus includes:
• a first capacitance provided between the first port terminal and the first terminal;
• a second capacitance provided between the first terminal and the conductor part;
• and
• a first inductance provided between the second port terminal and the second terminal, and
• wherein the switching circuit apparatus further comprises:
• a first capacitor connected between the first port terminal and the second port terminal;
• and
• a second inductor connected between the second terminal and the conductor part,
• wherein the first port terminal and the second port terminals are connected to a power supply apparatus,
• wherein the third port terminal and the fourth port terminal are connected to a load apparatus, and
• wherein the switching circuit apparatus operates as a boost converter.
