The present invention provides a novel direct current boosted circuit. The circuit comprises a direct current voltage source, multi-voltage modules, a Boost circuit module and a load module. After the direct current voltage source passes through a plurality of multi-voltage modules which is charged in parallel and discharged in series to boost the voltage, and is boosted again by the Boost circuit to transmit to the load module. The rated voltage required to bear of a switch tube in the direct current boosted circuit does not exceed the peak value of the input voltage, the multi-voltage circuit is able to boost the low voltage to required high voltage, and the Boost circuit is able to regulate the voltage to continue the output voltage and allow the performance to be more stable and reliable; and moreover, the requirements of the voltage with different grades are satisfied through adding the multi-voltage modules, and the universality is high.
