The invention belongs to the field of a power supply circuit, and discloses a direct current isolation power supply. The direct current isolation power supply comprises a low-pass filtering module, afirst voltage boosting module, an isolation voltage conversion module, a second voltage boosting module, an output switch module and a voltage reduction module; the low-pass filtering module is externally connected with a direct current voltage with of the first preset value, and after the noise is filtered, the direct current voltage is transmitted to the first voltage boosting module; the firstvoltage boosting module performs voltage boosting on the direct current voltage of the first preset value into a second preset value, and then outputs the processed direct current voltage to the isolation voltage conversion module; the isolation voltage conversion module converts the direct current voltage of the second preset value into an alternating current and outputs the alternating current to the output switch module; the output switch module performs rectifying and voltage stabilizing on the alternating current into direct current voltages of the third and fourth preset values, and thenoutputs the processed direct current voltages; the second voltage boosting module converts the direct current voltage of the third preset value into the direct current voltage of the fifth preset value and then outputs the processed direct current voltage; and the voltage reduction module performs voltage reduction on the direct current voltage of the fourth preset value into a direct current voltage of the sixth preset value, and then the output switch module controls the processed direct current voltage to be output.
Description
technical field [0001] The application belongs to the field of power circuits, and in particular relates to a DC isolated power supply. Background technique [0002] Some car TV power supplies used in RVs are basically designed with non-isolated solutions. Although the structure and cost have certain advantages, they have obvious defects in the stability and safety of the power board. [0003] Conventional vehicle power supplies cannot be applied to high-end vehicle equipment due to limitations such as low efficiency, high temperature, large loss, and unstable output voltage. Contents of the invention [0004] In view of this, the embodiment of the present application provides a DC isolated power supply to solve the problem of unstable output voltage of conventional vehicle power supplies. [0005] An aspect of the embodiments of the present application provides a DC isolated power supply, including: [0006] A low-pass filter module, a first boost module, an isolated vo...
