Description: The circuit depicted in the figure includes an automatic voltage regulator (T) that maintains a constant output by utilizing a servo motor. The circuit features transistors VT1 and VT2 (3DK9), with a capacitance range of C (65 ~ 85). Transistor VT3 is specified as 3AX818, with a capacitance range of 60 ~ 80. The circuit incorporates diodes VD2, VD3, and VD6 to VD9 (1N4002); VD4, VD5, and VD10 (1N4148); VD11 (1N4001); and a light-emitting diode VD1 (BT304). A Zener diode VD12 is specified as 2CW119. Capacitors include C1 (1 µF, 400V), C2 and C3 (0.1 µF, 250V), C4 and C5 (220 µF, 25V), C6 (470 µF, 50V), and C7 and C8 (47 µF, 50V). Resistors R1 (10k), R2 and R7 (510), R3 and R6 (2.7k), R4 (470), and R5 (51) are listed, with R1 needing to be rated for more than 3W power, while the others are selected as 1/2 to 1/4W metal film resistors. Potentiometers RP1 and RP2 are rated at 1k. The relays K1 to K3 are specified as JRK-13F, the AC contactor KA as 522, and the servo motor M as ND-D. A voltmeter PV is listed as 85L1-0 to 250V, with switches S1 (KN3-3) and S2 (KN-2W1D), and a fuse FU rated at BGOP µ6-5A.
The circuit serves as an automatic voltage regulation system, designed to maintain a stable output voltage under varying load conditions. The main component, the automatic voltage regulator (T), adjusts the output voltage through feedback from the servo motor, which is mechanically linked to the output stage. This feedback loop ensures that any fluctuations in load do not affect the output voltage, providing a reliable power supply.
Transistors VT1 and VT2 (3DK9) are employed for switching and amplification purposes, ensuring efficient control of the voltage regulation process. The additional transistor VT3 (3AX818) further supports the regulation by enhancing the circuit's response to load changes.
The diode arrangement, including the 1N4002 and 1N4148 types, provides rectification and protection against reverse polarity, ensuring the circuit's longevity and reliability. The light-emitting diode (BT304) serves as an indicator, signaling the operational status of the circuit.
Capacitors are strategically placed throughout the circuit to filter voltage spikes and maintain stability. The selection of capacitors with varying capacitance values allows for effective smoothing of the output voltage, particularly under transient conditions.
The resistors are critical for setting biasing levels and controlling current flow within the circuit. The choice of metal film resistors for most components ensures precision and stability, which is vital for the performance of the voltage regulator.
Potentiometers RP1 and RP2 allow for manual adjustment of the circuit, enabling fine-tuning of the output voltage as required. The relays (JRK-13F) facilitate switching operations, controlling the power delivery to the load based on the feedback from the servo motor.
The AC contactor (522) provides isolation and protection for the circuit, while the voltmeter (85L1-0 to 250V) allows for monitoring the output voltage, ensuring that it remains within specified limits. Switches S1 and S2 enable user interaction with the circuit, providing options for manual control and operation.
Overall, this automatic voltage regulator circuit is designed for efficiency, reliability, and ease of use, making it suitable for various applications where voltage stability is critical. Circuit shown in Figure, T is auto voltage regulator. Its output fixed input end by a servo motor to automatically adjust the output remains constant.
