Method and apparatus for preventing improper switching of a dual power supply |
摘要 |
The present invention provides a dual switching power supply system that is immune to malfunction caused by the off noises of the switch control signals. The dual switching power supply system of the invention generates stable voltage outputs without the necessity of making any difficult and unsatisfactory adjustment in the PCB layout process. The dual switching power supply system of the invention preferably comprises: a first switch control means for outputting a first switch control signal; a second switch control means for outputting a second switch control signal; and a phase shifting means for shifting the phase of the second switch control signal by a predetermined amount while keeping the frequencies of the first and switch control signal equal.
