Abstract
The invention discloses a kind of DC-to-DC voltage changer, be used for direct voltage being risen or falling,, and can reduce that battery takes up space and the weight of electronic installation with the different voltage needs of the work of satisfying different electronic devices and components and electronic circuit.This converter comprises: the DC-AC conversion portion, and it has an oscillating circuit; The AC transformation part, it has a transformer; The AC-DC conversion portion, it has rectification and voltage stabilizing circuit.
Description
The present invention relates to a kind of multipurpose DC-to-DC voltage changer, especially relate to a kind of low-voltage direct converter.
In electricity field, voltage transformation is the problem that often runs into, and DC-AC conversion, AC-AC conversion and AC-DC conversion adopt especially that AC converter is seen everywhere especially in a variety of devices.But, along with developing rapidly of small household appliances, it is important that the DC-to-DC voltage changer seems day by day, reason is: the direct-current working volts difference that various electronic devices and components or electronic circuit (as integrated circuit) are required, the voltage range of battery mostly is 1.5 volts/joint, when operating voltage is higher (as 9 volts or 12 volts even 24 volts), need with more piece dry cell or rechargeable battery; Electronic instrument and household electrical appliances develop to miniaturization, this will reduce that battery takes up space and weight owing to these reasons, existing dry cell or rechargeable battery have been difficult to satisfy specification requirement, so, fewly provide various direct voltages as how trying one's best, become a key technical problem of electricity field with light battery.
The objective of the invention is to provide a kind of DC-to-DC voltage changer, this converter can be realized the lifting of direct voltage easily, and low its weight of the cost of this converter itself and institute take up space also less.
For achieving the above object, DC-to-DC voltage changer of the present invention comprises three converting electrical signal processes in fact, that is: direct current signal becomes AC signal; The AC-AC transformation; Interchange after the transformation converts direct current again to.According to the present invention, adopt an oscillating circuit to finish direct current and become the conversion that exchanges; Adopt an inductance transformer to finish the AC transformation process; Adopt rectification and voltage stabilizing circuit to finish the conversion of AC-DC.
Owing to adopt DC-to-DC voltage changer of the present invention to realize the lifting of direct voltage, therefore can reduce the kind and the quantity of battery, thereby also reduce to adopt volume and weight than the electronic installation of High Level DC Voltage.
The present invention will be further described below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is the functional-block diagram of the DC-to-DC voltage changer of proposition according to the present invention.
Fig. 2 is the electrical schematic diagram of one embodiment of the present of invention.
As shown in Figure 1, DC-to-DC voltage changer of the present invention comprises that it is oscillator signal (OS) that three processes are about to direct current (DC) conversion of signals, this interchange (AC) oscillator signal produces interchange (AC ') signal that increases or reduce through the transformation process, and this signal (AC ') converts direct voltage to after over commutation and voltage stabilizing.
Fig. 2 has shown the physical circuit of realizing the principle of Fig. 1, and wherein K is a switch, and BG1 and BG2 are transistor, and B is the winding type inductance transformer, and IC1 is a bridge rectifier, and DW is a voltage-stabiliser tube.After the K switch closure, the oscillating circuit that triode BG1 and BG2 and capacitor C 1 and C2 form, with for example 1.5 volts of direct voltage DCE() convert the AC signal of upper frequency to, this AC signal flows through the primary coil of transformer B, the amplitude of the AC signal that obtains on the transformer secondary output coil depends on the turn ratio of primary and secondary coil, by suitable turn ratio, can obtain required direct voltage (for example 3 volts, 4.5 volts, 6 volts, 9 volts, 12 volts etc.).After the AC signal process rectifier IC1 rectification on the secondary coil, again through obtaining pulsation-free direct voltage after filtering and the voltage stabilizing.
Fig. 2 is a kind of better simply execution mode of the present invention, and this invention is not limited thereto the scheme of principle realization the object of the invention of any Fig. 1 of passing through, all belongs to the present invention's spiritual scope.
