Title:
POWER CIRCUIT AND ELECTRIC APPARATUS HAVING THE SAME
Document Type and Number:
Japanese Patent JP2013219857
Kind Code:
A
Abstract:

To provide a power circuit that safely prevents a shock hazard even if an input terminal for DC power is touched.

A power circuit 100 includes a DC input terminal 20, an AC input terminal 10, a rectification circuit 30 for converting AC power to DC power, and an output terminal 40 connected at one end to a junction P1 of a positive terminal 21 and a high potential side output end of the rectification circuit 30 and at the other end to a junction P2 of a negative terminal 22 and a low potential side output end of the rectification circuit 30, and outputs from the output terminal 40 DC power input into the DC input terminal 20 or the DC power converted by the rectification circuit 30. The power circuit 100 further includes a current interruption section D1 connected in series between the positive terminal 21 and the junction P1 to interrupt a current flowing from the junction P1 to the positive terminal 21, and a current interruption section D2 connected in series between the negative terminal 22 and the junction P2 to interrupt a current flowing from the negative terminal 22 to the junction P2.
