POWER SUPPLY DEVICE AND METHOD FOR CONTROLLING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18155456 titled 'POWER SUPPLY DEVICE AND METHOD FOR CONTROLLING SAME
Simplified Explanation
The patent application describes a power supply device that includes a rectifier circuit, a capacitor circuit, an inverter, a switch, a sensor, and a controller.
- The rectifier circuit converts the inputted alternating current power supply into a rectified form.
- The capacitor circuit consists of two capacitors connected in series and smooths the rectified power supply.
- The inverter converts the output power of the capacitor circuit to a preset power and outputs it.
- The switch selectively connects a middle node of the first capacitor and the second capacitor with an end of the alternating current power.
- The sensor detects the size of the alternating current power.
- The controller determines the power mode of the alternating current power based on the sensor's output and controls the switch accordingly to multiply and amplify the selectively rectified power.
Potential applications of this technology:
- Power supply devices for various electronic devices and appliances.
- Renewable energy systems such as solar or wind power systems.
- Uninterruptible power supply (UPS) systems for backup power.
Problems solved by this technology:
- Efficiently converting and smoothing alternating current power supply.
- Adapting to different power modes and sizes.
- Enhancing power supply stability and reliability.
Benefits of this technology:
- Improved power conversion efficiency.
- Enhanced power supply stability and reliability.
- Adaptability to different power modes and sizes.
- Potential for use in various applications and industries.
Original Abstract Submitted
A power supply device is provided. The power supply device includes a rectifier circuit for rectifying an inputted alternating current power supply, a capacitor circuit comprising a first and second capacitor which are connected in series, and smoothing the alternating current power supply rectified in the rectifier circuit, an inverter for converting the output power of the capacitor circuit to a preset power and outputting same, a switch for selectively connecting a middle node of the first capacitor and the second capacitor and an end of the alternating current power, a sensor for detecting a size of the alternating current power, and a controller which confirms a power mode of the alternating current power on the basis of an output value of the sensor, and which controls the switch so that the capacitor circuit multiplies and amplifies the selectively rectified alternating current power based on the confirmed power mode.
