Inventor: MASAKI KATSUHARU
IPC: H02M7/162
Filed: 1990-09-26
Abstract: PURPOSE:To suppress a rush current when a power source is turned ON and to rapidly interrupt an overcurrent by composing at least part of rectifiers of a bridge type rectifier circuit of a controlled rectifier, and controlling a conducting angle. CONSTITUTION:A bridge type rectifier circuit RC is composed by bridge- connecting thyristors SCR1, SCR2 as controlled rectifiers and diodes D3, D4. Reverse polarity self-extinguishing type semiconductor elements S1, S2 are connected in parallel at both ends of the diodes D3, D4. The conducting angles of the elements SCR1, SCR2 are controlled when an AC power source is turned ON to suppress a rush current. The conducting angle is reduced when the AC power source is turned ON, and the angle is so controlled as to increase the angle through a predetermined time. The angle is gradually increased from 0 degree to 180 degrees in a predetermined period of time. Thus, the rush current when a power source switch SW is closed can be effectively suppressed.
