Abstract
PURPOSE: To accomplish highly accurate detection by inserting the primary winding of the current transformer into respective circuits in which the load current flows to each other while only the current is drawn from the secondary winding of the current transformer.
CONSTITUTION: The primary winding of the current transformers 9 and 10 are inserted into the respective circuits in which the load current flows to each other. The voltage develops in the secondary winding of the current transformers 9 and 10 whereby current runs. Diodes 11 and 12 are inserted in the forward direction to the current in series while the side current circuit comprising diodes 13 and 14 and resistors R15 and R16 are inserted into the respective secondary windings. In addition, a common resistor R17 is connected to the secondary winding through the diodes 11 and 12. The terminal voltage of the resistor 17 is used as the detection voltage proportional to the load current.
