The ENMod system is an AC front-end solution combining passive Power Factor Correction and autoranging function. It consists of the MiniHAM passive harmonic attenuation module and the FARM3 autoranging AC-DC front-end module. Combined with filtering and hold-up capacitors, the ENMod system provides full compliance to EN61000-3-2 Harmonic Current, EN55022, Level B Conducted Emissions, EN61000-4-5 Surge Immunity, EN61000-4-11 Line Disturbances, and EN61000-3-3 Inrush Current.
Unlike active PFC solutions, the MiniHAM generates no EMI, greatly simplifying and reducing system noise filtering requirements. It is also smaller and more efficient than active alternatives. Optimized for operation on the DC bus (provided by the FARM3) rather than directly on the AC line, it will provide harmonic current compliance at up to 600 W of input power at 230 Vac.
The FARM3 is a filter and autoranging module that has been optimized for use as the front end for the MiniHAM. Both modules are in Vicor’s standard Mini half-brick package.
