PHASE-SHIFTING A SYNCHRONIZATION SIGNAL TO REDUCE ELECTROMAGNETIC INTERFERENCE |
摘要 |
A power supply with reduced electromagnetic interference (EMI) is described. This power supply includes cascaded stages with switched-mode power-supply circuits that are switched synchronously during operation by switching signals that have a common fundamental frequency. EMI associated with the power supply is reduced by establishing a phase shift between the switching signals in at least two of the stages. |
