Abstract
A power supply system for supplying a load current to a load including a serially connected circuit of a controlled rectifier, a switch and a capacitor. A diode is connected in parallel with the capacitor or with a serially connected circuit of the switch and the capacitor and a control circuit. Which controls the controlled rectifier such that when a first voltage between the capacitor is larger than or equal to a specified voltage the controlled rectifier is operated as bypass pair mode and when the first voltage is below the specified voltage the controlled rectifier is operated as current control mode. A method for starting a power supply system is also disclosed.
