The switching mode power supply includes a first PWM controller and a second PWM controller that are driven by different driving voltages and control first and the second voltages to be output, respectively, a first transformer that is controlled by the first PWM controller to output the first voltage and having a primary coil, a secondary coil to induce the first voltage, and an auxiliary winding, and a rectifier that rectifies and smoothes a current flowing through the auxiliary winding of the first transformer, generates a power save mode voltage based on the respective driving voltages of the first and the second PWM controllers, and supplies the power save mode voltage to the first and the second PWM controllers. Accordingly, the power save mode is operated using a voltage difference without requiring an extra controller.

摘要： A high voltage power supply and a high voltage power control method thereof. The high voltage power supply includes a high voltage generation part to generate a high voltage, and a pulse width modulation (PWM) generation part to generate a pulse width modulation signal according to an output control value and to control the high voltage generation part to generate the high voltage using the generated pulse width modulation signal, when a high voltage output setting signal having the output control value is received by the PWM generation part to indicate the high voltage to be generated. Therefore, it is possible to automatically output a high voltage as desired without requiring an offline setting. In addition, although a voltage set and/or an output load are changed, the changed voltage set and/or the output load are automatically compensated so that a constant high voltage output can be output with a variety of different devices having different loads and power requirements.
