Design of new current power supply with low ripple and high voltage

We design a new current power supply circuit with low ripple and high voltage.The power supply works under the principle of complementary voltage,which parallels two self-contained inverting circuits of half-bridge with the same output voltage and phase difference 90°.The paralleling connection of the output voltage reduces the ripple of output voltage.We introduce the principle and control mode of our power supply and manufacture a prototype low power machine.The results of the experiment of the prototype machine show that the design is feasible.
