Line Filter for High Boost HAM

A line filter is required to provide attenuation of conducted

emissions generated by the HAM module and to protect it from

line transients. It also presents a well defined high frequency

AC line impedance to the input of the HAM. To meet the listed

specifications, Vicor’s P/N 30205 line filter/transient suppressor

or equivalent must be used, see Figure 9. The addition of a MOV

external to this filter is required to meet normal mode transient

surge requirements.

For applications using HAMD + BAMD or where the user desires

to construct a custom HAM filter, the filter should be designed

following Figure 9, the schematic of Vicor’s P/N 30205 filter.

The current carrying capability of the inductors must be scaled

proportionally to the number of HAM modules used. Inductance

values must be selected according to Table 1. These limits are

to ensure proper operation of the HAM and do not guarantee a

system will meet conducted emissions specifications.

For applications requiring magnetic field shielding, do not place a

ferrous EMI shield over the plastic cover of the HAM module. This

can cause thermal problems due to induction heating effects.
