Document Type and Number:
Japanese Patent JP2002034167
Kind Code:
A
Abstract:
To increase efficiency and reliability of a power circuit.
A bridge construction using two sets of relay contacts for supplying a DC power voltage of a specified polarity to a load is formed in the power circuit. In a transition duration just after power is supplied, current is caused to flow in a load through a current limiting resistor. After the passage of the transition duration, DC power voltage is applied to a load using the bridge construction.
