In electronics, a multi-transistor configuration called darlington pair, or the Darlington configuration (commonly called a Darlington pair) is a compound structure of a particular design made by two bipolar transistors connected in such a way that the current amplified by the first transistor is amplified further by the second one. This configuration gives a much higher current gain than each transistor taken separately.
Power transistor control device
FIELD: electrical engineering.SUBSTANCE: development of pulsed electrical energy converters as a driver for controlling a power transistor. The invention aims to solve is to expand the scope of application of the driver and increase its reliability. Unipolar power supply of the driver is achieved by replacing the comparator with a Darlington transistor circuit, connected to the input through a series resistive-capacitive circuit to the point where the amplified control signal is supplied, and to the common point of the circuit via a resistor and a diode parallel to it. The amplification of the input control pulse is achieved by connecting a field-effect transistor between the control signal supply point, the common point of the circuit, and the terminal of the primary winding of the gate transformer, opposite to the one connected to the power supply point through a current-limiting resistor, which amplifies the input control signal.EFFECT: expansion of the driver's application area in push-pull circuits due to the presence of active locking, simplification of the driver's power supply circuit, and simplification of the control circuits due to the inclusion of an amplifier in the driver.1 cl, 1 dwg

This application relates to the field of power switching technology, and discloses a firmware-controlled peripheral interface power adaptive switching system and method. The method involves: upon detecting a peripheral connection, providing a basic power supply voltage to the peripheral and initializing the UART serial communication interface; sending a model query command to the peripheral and extracting the peripheral model identifier string from the response frame to generate a relay control command; controlling a Darlington transistor array driver chip to drive the coil of a double-pole double-throw relay, switching the connection state of the relay's common terminal contact, and reading the voltage and current measurements of the peripheral; calculating the peripheral's power value, and encapsulating the power value and power supply mode status into a status data packet and transmitting it to the peripheral management software. This application transforms power supply configuration from hardware mechanical operation to firmware intelligent control, realizing plug-and-play, zero-error configuration, and visual management of peripheral power supply, reducing production costs and maintenance difficulty, and improving the intelligence level of peripheral interface power management.
