1. Stable New IC Plan
    The integrates circuit board and timing circuit generates clock rate unconditionally.
    And the rate is regular and stable.

2. PMW Radiation
    The time ratio of the switch is controlled by PWM to maintain stable output, so that the power of the power supply is               small and efficiency is high.

3. Reduce Radiation
    The EMC circuit system is improved to protect the equipment from electromagnetic interference, reduce radiation and           protect the equipment.

4. Improve Power Availability
    The PFC circuit is designed to maximize power utilization.
