This article describes the rectifier gyrator circuit. The circuit is relatively simple, it is easy to grasp. Here you'll read the following diagram combine text bar. In order to avoid excess ripple output power to the one in a heavy-duty, which is usually a large value capacitor selection below rectifier. In this circuit, C1 is a 470 uf capacitor. ? Gyrator effect values ??using the principle is the basis of the input capacitance multiplied by the effective transitor current gain of the transistor. This is 100 u C2 appears at the output (the Vreg) is 100 x 2N3055 power transistor's current gain. If you assume that the DC current gain of 50, and then through the supply smooth, as if you chose a 5000 uf capacitor. The following figure shows the output voltage and current through the load: - Load a near 400 mA. ? With the output directly from the rectifier has about 5 v pk pk ripple at the output. ?? Use the output transistor emitter stuff is the best. This circuit will stabilize the output voltage of several hundred milliseconds, the maximum. This advantage is a smaller, lower cost can use this reservoir capacitor circuit to supply a high-quality smooth. If you want a thorough understanding of the principles of the circuit, I suggest you can go to find out the important components of the circuit, such as: 2N3055 .
