IPC: G05F1/70
Filed: 1981-07-23
Abstract: PURPOSE:To reduce the capacity of a switch by connecting a phase advancing condenser in parallel with a cycloconverter and simultaneously energizing or deenergizing them by a switch. CONSTITUTION:A disconnecting switch DS is closed in the state of a current IS, and a power switch SW is then closed, allowing a cycloconverter C/C to be standby. When a switch MC is closed, a delayed reactive current and a led reactive current respectively flow through the cycloconverter C/C and the phase advancing condenser C, and only the effective component of the power current IS flows. The power source is opened at the time of stopping the operation by setting the load current command to zero and then opening the switch MC. In this manner, when the transient state is ignored, only the effective current IS flows through the switch MC, and the current capacity of the switch can be remarkably reduced.
