- शक्ती प्रवर्धक मोठ्या प्रमाणात शक्ति हाताळत असल्याने भारामध्ये जास्तीत जास्त शक्ति हस्तांतरित करणे महत्वाचे आहे.
- असे करण्यासाठी, शक्ति प्रवर्धक आणि लोडच्या o/p प्रतिबाधामधील प्रतिबाधा जुळत असल्याची खात्री करणे आवश्यक आहे.
- कारण लाऊडस्पीकरसारख्या भारांना कमी प्रतिबाधा येत आहे.
- शक्ति प्रवर्धकामध्ये भाराशी जुळण्यासाठी कमी उत्पादन प्रतिबाधा देखील आहे.
- सामान्य कलेक्टर किंवा एमिटर फॉलोअर परिपथ सामान्यतः शक्ति प्रवर्धक म्हणून वापरले जाते कारण त्यात कमी o/p प्रतिबाधा असते.
- हीट सिंक आणि मोठ्या आकाराच्या पॉवर ट्रान्झिस्टरच्या वापरामुळे, शक्ती प्रवर्धक भारी बनतात.
- o/p बाजूच्या प्रतिबाधा जुळण्यासाठी ट्रान्सफॉर्मर देखील वापरला जाऊ शकतो.
