Summary: The work presents the development and investigation of a programmable power block with remote control based on Quick Charge technology. It was figured out that power sources/chargers for mobile phones with Quick Charge 2.0, 3.0 technology can be used to construct a programmable power block with remote control. For this purpose, an additional control module needs to be developed. In this case, the output voltage level can be programmatically set through the high-voltage dedicated Qualcomm charging port (HVDCP). The remotely set output voltage is extracted from the HVDCP port lines: Vbus, Gnd (pins 1, 4). The control of the output voltage is achieved through voltage levels of specific duration using the D+, D- lines of the HVDCP port. The developed scheme of the programmable power source based on Quick Charge technology requires specialized software. The control module program should provide identification of power adapters that support Quick Charge 2.0, 3.0 technology. In this case, the HVDCP continuous mode allows remote control of the output voltage from 3.6V to 20V when using the control module with corresponding software. The article presents the scheme and software for the control module of the programmable power block based on Quick Charge technology, which operate in accordance with the developed algorithms. Modeling and experimental research confirmed the possibility of remote change of the adapter`s output voltage using the proposed control module and corresponding software. Thanks to the online processing and monitoring of obtained data on a personal computer, both manual and automatic control of the output voltage level are possible. Remote control of the programmable power block can be done through the USB port or wireless interfaces like Bluetooth, Wi-Fi. For this purpose, the microcontroller of the control module must support a UART interface to which shields, modules, or interface converters can be connected to interact with remote control elements.
