Power converter integrated with flyback converter

A power converter comprising:

• a flyback converter converting an input power of a power supply input terminal into a standby power through a primary side circuit connected to the power supply input terminal and a secondary side circuit magnetically coupled to the primary side circuit to supply the standby power;
• and
• a main converter converting the input power of the power supply input terminal into a main power to supply the main power, and converting the input power of the power supply input terminal into the standby power through the secondary side circuit of the flyback converter to supply the standby power,
• wherein the secondary side circuit of the flyback converter is integrated in the main converter, and
• wherein the main power and the standby power are respectively supplied through the main converter during a normal mode, and the standby power is supplied using the primary side circuit and the secondary side circuit of the flyback converter during a standby mode.
