Problems solved by technology

[0003] At present, the adaptability of many DC / DC DC power regulator converters produced in various countries in the world can only be 1:2, such as from 9V to 18V, from 18V to 36V, from 36V to 76V, etc. So far, DC / DC power modules that can adapt to a wide range of input voltage and have been on the market, such as the products of a French company, although their input voltage adaptability is close to 1:5, they cannot adapt to ultra-wide range voltage input ( From 5.85V to 40V, its input voltage adaptability is close to 1:7) and the requirements of multiple voltage output

Embodiment Construction

[0014] The embodiments of the present invention are further described below in conjunction with the accompanying drawings: the unstable input voltage is shunted into the DC conversion stabilized output circuit of the converter after passing through the anti-input reverse connection and peak suppression circuit, and the anti-input reverse connection and peak suppression circuit is composed of Transient voltage suppression first diode V 1 composition. The DC conversion and voltage stabilization output circuit is divided into two circuits, one of which passes through the high-frequency series energy storage switching regulator and then outputs a stable 3.3V voltage through the linear low-dropout voltage regulator. The high-frequency series energy storage switching regulator The device is controlled by a high-frequency series switch chip U 5 and its peripheral energy storage filter circuit, the energy storage filter circuit includes the ninth filter capacitor C at the input end ...

Description

technical field [0001] The invention relates to a DC stabilized power supply, in particular to a DC / DC DC power stabilized converter adaptable to a wide range of input voltages. Background technique [0002] The normal operation of mobile electronic equipment needs to provide DC regulated power supply with stable output voltage. In many special application environments, it is often encountered that the input voltage for power supply to electronic equipment greatly exceeds the normal range during the operation of the equipment. The changing situation is like the voltage provided by various vehicle power supply systems such as tanks, armored vehicles, special engineering vehicles, communication command vehicles, and missile launch vehicles. The above-mentioned vehicles all use a large number of computers, digital information systems, command and control systems and various electronic devices. In order to ensure the normal operation of these devices, it is necessary to be equip...
