TH19401U - Variable voltage power supply system - Google Patents

Abstract

The variable voltage power system (VDS-C) consists of a charging circuit, battery, and voltage regulation circuit. A wireless receiver is added to receive electromagnetic waves from an external transmitter, inducing an electric current. This current is then stored in the battery, and a display shows the voltage and battery capacity. The VDS-C system can be charged both wired and wirelessly for convenience and increased safety, as it doesn't require constant power cord connection. It can operate whether connected to a power source or disconnected, thanks to the internal battery backup.

Claims (3)

------30/06/2564------(OCR) 1. The variable voltage power supply system consists of a charging circuit (2), a battery (3), and a voltage regulator circuit (4). The charging circuit (2) has ports for connecting to an external power source to charge the battery (3) with an external current. The battery (3) stores the electrical energy to power the voltage regulator circuit (4), which is connected to the battery (3). The voltage regulator circuit (4) adjusts the voltage to be sent to the connected electrical appliances. The voltage regulator circuit (4) is connected to a number of ports, which are ports for connecting to the power cords of external electrical appliances. It has a unique characteristic: a wireless electrical receiver (8) is connected to the charging circuit (2). The wireless electrical receiver (8) receives electromagnetic waves from an external transmitter, induces them, converts them into an electrical current, and sends it to the charging circuit (2) to charge the battery (3). 2. The variable voltage power supply system, according to claim 1, also consists of a display (5) connected between the voltage regulator circuit (4) and the ports for connecting to the power cords of external electrical appliances to display the voltage (volts) entering the external electrical appliances. 3.
