संकल्पना:

तरंग आवृत्ति: तरंग आवृत्ति एक परिवर्त्तक की आउटपुट आवृत्ति है जो आपूर्ति आवृत्ति का कुछ अभिन्न गुणक है।

\(\) \(f_{ripple}\) = n × fs

\(f_{ripple}\) = तरंग आवृत्ति

fs = आपूर्ति आवृत्ति

n = समय अवधि में संपदों की संख्या

गणना:

3ϕ पूर्ण परिवर्त्तक में आउटपुट तरंग की समयावधि में 6 संख्या में स्पंद होती हैं।​

fs = 50 Hz

\(f_{ripple}\)= 6 × 50

\(f_{ripple}\)= 300 Hz

Additional Information 1ϕ पूर्ण परिवर्त्तक में आउटपुट तरंग की समयावधि में 6 संख्या में स्पंद होती हैं।​

तो, \(​​​​f_{ripple}\) = 2 × fs

\(f_{ripple}\) = 2 × 50

\(f_{ripple}\) = 100 Hz
