Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply circuits, and more specifically to a power supply device with multiple AC and DC power supplies. Background Technology
[0002] AC power supplies convert AC to DC power for use in circuits, offering advantages such as high efficiency and long lifespan. DC power, on the other hand, has excellent stability, and voltage regulators can maintain the stability of the output voltage. If the output voltage falls below or rises above a certain value, the voltage regulator can automatically adjust the input voltage to ensure that the output voltage remains above the required level. However, existing power supply equipment can only provide a single power source. When multiple different power sources are needed, multiple independent power sources must be connected, which takes up a lot of space and is costly. To overcome these shortcomings, a power supply device with multiple AC and DC power sources is proposed. Utility Model Content

The output terminals of capacitor C2, resistor R1, and capacitor C1 are connected together and then connected to pin 4 of the rectifier VD1, and finally connected to the negative terminal a2 of the power output terminal.
[0005] Furthermore, the system also includes a transformer T2, a diode D2, resistors R3-R5, capacitors C3-C5, and an inductor L1. Pin 1 of transformer T2 is connected to the output terminal of resistor R2. Pin 3 of transformer T2 is connected to pin 4 of rectifier VD1. Pin 4 of transformer T2 is connected to the input terminal of diode D2 and then to the input terminal of resistor R3. The output terminal of resistor R3 is connected to the input terminal of capacitor C3. The output terminal of capacitor C3 is connected to the output terminal of diode D2 and then to the input terminal of inductor L1 and capacitor C4. The output terminal of inductor L1 is connected to power output terminal b1 and then to the input terminals of capacitor C5, resistor R4, and resistor R5.

[0008] The technical effects and advantages of this utility model are as follows:
[0009] This power supply device features multiple AC / DC power sources. Voltage source V1 provides AC power, and transformer T1 acts as an isolation step-down transformer. Since the input voltage of voltage source V1 is relatively high, after being isolated and stepped down by transformer T1, it is rectified by rectifier VD1 to convert the input AC power into DC power output. Then, it is filtered by an RC filter circuit composed of capacitor C1 and resistor R1 to reduce ripple. Finally, it is regulated by Zener diode D1. The regulated voltage is then connected to the load through the positive terminal a1 and the negative terminal a2 of the power output terminal. The load provides a stable and precise operating voltage; simultaneously, the power supply is converted to the required voltage by the parallel transformer T2. When the inductor L1 is fully charged, it is connected to the load through power output terminals b1 and b2 to supply power to the load, so as to achieve the simultaneous output of multiple stable DC power. At the same time, after being isolated and stepped down by the transformer T1, the input AC power is stored in the inductor L0 through the diode D3. The load RL is connected to pins 3 and 4 of the transformer T1, providing a stable AC power supply for the load RL; the whole system realizes multiple AC and DC power output.
