Problems solved by technology

[0002] In the current DC-DC converter, when the load of the output terminal of the DC-DC converter changes drastically or the load of the DC-DC converter is removed, the energy stored in the DC-DC converter usually cannot be released , causing the voltage at the output of the DC-to-DC converter to overshoot
The overshooting output voltage is likely to cause damage to the components inside the DC-DC converter or other loads at its output

Abstract

A direct current to direct current converter and an energy distribution method thereof. The DC-to-DC converter includes a switching circuit and an energy distribution circuit. The switching circuit is coupled to the DC power supply to receive the DC input voltage, and is controlled by the first control signal to generate the pulsating voltage. The energy distributing circuit is coupled to the switching circuit to receive the pulsating voltage and store electric energy, and is coupled to the DC power supply. The energy distribution circuit is controlled by the second control signal to convert the electric energy into a DC output voltage to supply power to the load, or is controlled by the second control signal to recover the electric energy to the DC power supply.

Description

technical field [0001] The invention relates to a power converter, in particular to a DC-to-DC converter with an energy distribution mechanism and an energy distribution method thereof. Background technique [0002] In the current DC-DC converter, when the load of the output terminal of the DC-DC converter changes drastically or the load of the DC-DC converter is removed, the energy stored in the DC-DC converter usually cannot be released , leading to an overshoot phenomenon in the voltage at the output end of the DC-to-DC converter. The overshooting output voltage is likely to cause damage to the components inside the DC-DC converter or other loads at its output. Contents of the invention [0003] In view of this, the present invention provides a DC-to-DC converter and its energy distribution method, which can suppress the increase in the DC output voltage of the DC-to-DC converter when the load of the DC-to-DC converter changes or is removed. Chong phenomenon. [0004...
