TH19401C3 - Voltage adjustable power supply system - Google Patents

Abstract

A summary of the invention which appears on the advert page ReadFile:Voltage adjustable power system consists of a battery charge circuit and a voltage regulator circuit. When an external transmitter induces an electric current, that current is sent to the battery and has a display for displaying the voltage and capacity of the battery by the power system. The adjustable voltage type can charge electricity to the system, both wired and wireless systems for ease of use as well as increased safety in use as there is no need to plug in the power cable all the time. It can be used while the power supply is connected or not connected to the power supply because there is a battery that serves as a backup power inside the system.

Claims (3)

All rights reserved and will not appear on the advertisement page:------30/06/2021------(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 a port for connecting to an external power source to bring external current to charge the battery (3). The battery (3) stores the electrical energy to supply to the voltage regulator circuit (4), which is connected to the battery (3). The voltage regulator circuit (4) adjusts the voltage to send 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 devices. It has a unique characteristic: it has a wireless electrical receiver (8) connected to the charging circuit (2). The wireless electrical receiver (8) receives electromagnetic waves from an external transmitter, induces them into an electrical current, and sends it to the charging circuit (2) to charge the electrical current into the battery (3). 2. A variable voltage power supply system under claim 1, which also includes a display (5) connected between the voltage regulator circuit (4) and the connection port for the external power device to show the voltage (volts) entering the external power device. 3. A variable voltage power supply system under claim 1 or 2, which also includes a display (7) connected to the battery (3) to show the level of power stored in the battery. 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 bring external current to charge the battery (3). The battery (3) stores the electrical energy to supply the voltage regulator circuit (4), which is connected to the battery (3). The voltage regulator circuit (4) adjusts the voltage to supply the connected electrical appliances. The voltage regulator circuit (4) is connected to several ports, which are ports for connecting to the power cords of external electrical devices. It has a unique feature: a wireless receiver (8) connected to the charging circuit (2). The wireless receiver (8) receives electromagnetic waves from an external transmitter, induces and converts the current, and sends it to the charging circuit (2) to charge the battery (3). 2. A voltage-adjustable power supply system in accordance with claim 1, in which a display (5) is connected between the voltage adjustment circuit (4) and the connection point for the power cord of an external electrical device. 3. A voltage-adjustable power supply system in accordance with claim 1 or 2, which has a display (7) connected to a battery (3) to show the level of energy stored in such battery.
