The invention relates to a switch stable power supply, which consists of a stable power converter and a stable power controller circuit. The conversion center of the stable power converter is the output inductance. The switch stable power supply can convert the input direct current and the rectified alternating current into the output direct current, which is used by the load. The current and the voltage of the output direct current can be regulated bidirectionally at random respectively from the minimum to the limited. In this way the switch stable power supply is plentiful in the function of output, wide in the range of regulation, good in the load adaptability and high in the power device efficiency. A switch, the voltage endurance of which is 600 V, can convert industrial frequency supply of 220 V. And the overall equipment is low heat run, little volume, lightweight and low cost.
