Single-phase AC front-end system incorporating the FARM and the MiniHAM

The ENMod system is a front-end solution combining passive Power Factor Correction and autoranging function. 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 and filtering requirements.
