Method for selecting energy-storage capacitance, filter inductance and filter capacitance of energy-storage degaussing power supply
2015
The invention discloses a method for selecting energy-storage capacitance, filter inductance and filter capacitance of an energy-storage degaussing power supply. The method comprises the following steps: (1) calculating pulse theoretical energy; (2) determining nominal voltage of an energy-storage capacitor group and the number of parallel capacitors; (3) calculating energy-storage capacitance matching power supply power of a power station and satisfying the pulse requirement; (4) grouping the energy-storage capacitor group and later convertors, and making a pulse discharge scheme according to a grouping result; and (5) performing calculation step by step according to the discharge scheme to obtain suitable filter inductance and filter capacitance. A multi-redundant mechanism is adopted in the method, safe redundancy in a general output circuit and the convertors is ensured.
