Показать описание
Components:
1. 5V Relay (likely used as a switch)
2. SR360 Diode (Schottky rectifier, low forward voltage drop)
3. 2x 1N4007 Diodes (standard rectifier diodes)
4. 220μH Inductor (energy storage)
5. 100μF, 80V Capacitor (output filter)
6. 47μF, 25V Capacitor (input filter/decoupling)
7. 5V Power Supply (input)
Circuit Operation:
1. The 5V input is filtered by the 47μF capacitor.
2. The relay acts as a switch.
3. When the relay is energized, current flows through the inductor, storing energy.
4. The SR360 diode and 1N4007 diodes form a rectifier circuit, converting the inductor's oscillations to a DC output.
5. The 100μF capacitor filters the output voltage.
Achieving 60V Output:
To reach 60V output from a 5V input, circuit is operating in discontinuous conduction mode (DCM). The inductor's energy is stored and released during each switching cycle, generating a higher output voltage.
Considerations and Potential Improvements:
1. Efficiency: Measure the input and output currents to estimate efficiency.
2. Stability: Ensure the output voltage remains stable under varying load conditions.
3. Heat Dissipation: Monitor component temperatures, especially the relay, diodes, and inductor.
4. Output Ripple: Measure the output voltage ripple to ensure it's within acceptable limits.
5. Protection: Consider adding overvoltage protection (OVP), overcurrent protection (OCP), and input undervoltage protection (UVP).
