DC/DC CONVERTER, ON-BOARD UNIT AND CHARGING DEVICE
First Claim
1. A DC/DC converter configured to allow separation of a primary side constitution unit and a secondary side constitution unit of a transformer,the primary side constitution unit including:
- a primary winding of the transformer;
a primary side switching element that intermits a current flowing from an external power source to the primary winding; and
a primary side control unit that controls power supplied to the primary winding to an arbitrary value by operating the intermittent operation of the primary side switching element, andthe secondary side constitution unit including;
a secondary winding of the transformer;
a secondary side switching element that intermits a current flowing from the secondary winding to a load connected to the secondary side constitution unit; and
a secondary side control unit that controls power supplied to the load to an arbitrary value by operating the intermittent operation of the secondary side switching element,wherein the primary side control unit detects an electrical behavior inside the primary side constitution unit generated by the intermittent operation of the secondary side switching element, and controls power supplied from the primary winding to the secondary winding by operating the primary side switching element on the basis of this electrical behavior.

Abstract
A DC/DC converter 1 is configured to allow separation of a primary side constitution unit 3 and a secondary side constitution unit 4 of a transformer 2. A secondary side switching element FET 2 is provided in the secondary side constitution unit 4, and controls power supply to a load 12 by intermitting an output of a secondary winding L2. The primary side constitution unit 3 detects an electrical behavior of the primary side generated by the intermittent operation of the secondary side, and controls the power supplied from the primary winding L1 to the secondary winding L2 by operating the intermittent operation of the primary side switching element FET 1 such that a cycle or duty of the intermittent operation of the secondary side falls within a predetermined range.
