Abstract: Introduction was made to switching transformer technology and high-voltage motor soft-starting devices based on the technology. The phase control voltage regulation principle of silicon controlled rectifier (SCR) was used to effectively solve the problem that the motor couldn’t operate normally, to realize one device to control multi-motor and to start consecutively. Analysis of the actual example of one to control five soft-starting devices in debugging operation conditions and comparison with other voltage reduction starting show that the device is with higher reliability and performance price ratio.
Key words: switching transformer; soft start; high-voltage motor; silicon controlled rectifier
