A new shunt DC active power filter scheme of power supply in steady high magnetic field facility

In view of the series DC active power filter in other SHMF and shunt PWM DC active power filter, the shunt linear adjustment active power filter scheme was proposed. The structure and principle of shunt linear adjustment active power filter was introduced. The realizing scheme of the DC active power filter was also analyzed. Simulation model of the shunt linear adjustment active power filter is established, and the simulation results verify the parameter design is reasonable. An experimental prototype is developed, the experimental results show that the filter has good filter effect.
