Modified ST202A Power Supply, 3-Wire Input with Two Cascaded LC EMI Filters
Reka bentuk rujukan oleh: Power Integrations
Application circuit shows Typical 3-wire input power supply with cascaded LC EMI filters. The sum of common mode inductance L2 and L3 should be 10mH or less and L3 should be at least twice the value of L2 to prevent superposition of filter resonant frequencies
