I need to design a power supply 110v , with an output between 6 and 9v. I did a design and I implemented a resistor after the bridge as a surge protector for the diode. I need to know if this is the right design and I need some calculations for the elements to provide an output between 6 and 9v.

### Power Supply Design and Simulation Educational Module #### Design Specifications: Design and simulate a regulated power supply using a bridge rectifier, capacitors, and a Zener diode (no Integrated Circuit). The source voltage is 110±10 Vrms, 60 Hz frequency. The output voltage is as follows (±5%): **Type 2: Between 6V and 9V** #### Circuit Diagram Explanation: The provided circuit diagram demonstrates the components and connections necessary to create the desired regulated power supply: 1. **Transformer**: The circuit starts with a transformer which steps down the input AC voltage to a lower AC voltage suitable for the rectifier. 2. **Bridge Rectifier**: Following the transformer, a bridge rectifier converts the AC voltage to pulsating DC voltage. The bridge rectifier consists of four diodes arranged in a bridge configuration. 3. **Smoothing Capacitor**: A capacitor is connected across the output of the bridge rectifier to filter the pulsating DC, resulting in a smoother DC voltage. 4. **Zener Diode Voltage Regulation**: A Zener diode is used for voltage regulation. It is connected in parallel with the load to provide a stable output voltage. The series resistor is used to limit the current through the Zener diode to ensure it operates in the breakdown region. 5. **Surge Protector**: A surge protection component is included to safeguard the circuit against voltage spikes. 6. **Output Terminals**: Finally, the regulated DC output is available across the output terminals. #### Diagram Representation: - The diagram shows the primary winding of the transformer connected to the AC mains supply. - The secondary winding of the transformer is connected to the bridge rectifier. The bridge rectifier consists of four diodes arranged in a diamond shape. - Following the rectifier, a capacitor is connected to smooth the rectified output. - A resistor is connected in series with a Zener diode (marked with arrows indicating voltage regulation) to maintain a stable output voltage. - A capacitor labeled as "Surge Protector" is connected across the Zener diode to indicate its role in surge protection. - The output terminals indicate where the regulated DC voltage will be available for use. This illustrated guide helps in understanding the practical aspects of designing and simulating a basic regulated power supply circuit to obtain a stable DC output from an AC source.
