Problems solved by technology

[0006] The technical result that the above prior art fails to achieve is stabilization at the DC stabilizer resulting in lower power dissipation and voltage drop at the DC stabilizer when the load impedance changes
[0007] The reason for not realizing the above technique is due to the lack of (stabilization) in DC stabilizer variable load to obtain constant current and resultant higher efficiency in the power supply circuit after reducing the dissipated power by the voltage drop of the DC stabilizer attention

Abstract

The invention relates to a device for producing direct current passing into load power-supply circuits. The invention relates to the field of electrical engineering. The device comprises a DC voltage source, a DC voltage-to-pulsed voltage converter, a pulsed voltage-to-DC voltage converter, and a DC stabilizer. A first input of the DC stabilizer is connected to an output of the pulsed voltage-to-DC voltage converter, a second input of the DC stabilizer is connected to a positive output of the DC voltage source, and a first output of the DC stabilizer is connected to one of the load terminals. The other terminal of said load is connected to a negative output of the DC voltage source. The device also comprises a control circuit, wherein a first input of the control circuit is connected to the output of the pulsed voltage-to-DC voltage converter, a second input of the control circuit is connected to a second output of the DC stabilizer, a first output of the control circuit is connected to a second output of the DC voltage source, and a second output of the control circuit is connected to a second control input of the pulsed voltage-to-DC voltage converter. The result is the stabilization of dissipation power in the stabilizer.
