CURRENT DETECTION DEVICE AND CURRENT DETECTION DEVICE FOR INVERTER

Title:

CURRENT DETECTION DEVICE AND CURRENT DETECTION DEVICE FOR INVERTER

Document Type and Number:

Japanese Patent JP2003232814

Kind Code:

A

Abstract:

To improve detection accuracy of a current detection device wherein a motor loaded on an automobile or the like is used for an inverter device driven by using a low-voltage battery as a power source.

A potential difference taking-out wiring pattern for taking out a potential difference between both ends of a shunt resistance mounted or provided on a printed circuit board is drawn out from a spot where a current to be detected hardly flows on a shunt resistance mounting land. Otherwise, the wiring pattern for taking out the potential difference between both ends of the shunt resistance is drawn out from a land fringe part positioned on the prolonged line of a wiring pattern for the current to be detected connected to the shunt resistance mounting land.
