Rectifier Circuit and Power Source Circuit

A power source circuit comprising:

• an inductor;
• and
• a rectifier circuit including a first terminal and a second terminal, the first terminal or the second terminal being connected to the inductor,
• the rectifier circuit including
• a first diode connected between a first terminal and a second terminal so that a direction toward the first terminal from the second terminal is in a forward direction;
• a switching element including a first main electrode connected to the first terminal, a second main electrode connected to a cathode of the first diode, and a gate electrode connected to an anode of the first diode;
• and
• a second diode connected in parallel with respect to the switching element so that a direction toward the first terminal from the cathode of the first diode is in a forward direction, between the first main electrode and the second main electrode of the switching element.
