Abstract
A high voltage power supply is provided. The high voltage power supply includes a soft-start circuit unit which outputs a natural voltage that decreases exponentially as time elapses and converts the natural voltage into a forced voltage having a predetermined scale if an enable signal is applied, a controller which compares the natural voltage output from the soft-start circuit unit with a reference voltage and outputs a control signal, and a converting unit which delays outputting a final voltage during a first predetermined time period and outputs the final voltage, which gradually increases as time elapses according to the control signal.
