  1. 1. MmE-ACTREC-PPP-VVV Megamic Electronics Pvt Ltd Date 1-02-2017 Doc ActRect_MODEL_00.pdf www.megamic.in Active Rectifier Regulator for Permanent Magnet Alternators Active Rectifier Regulator Conventional alternators have a field winding which can be used to regulate the alternator output. PM Alternators use permanent magnets instead of a field winding and operate at higher power-size ratios, compared to conventional designs. However, as they lack a field winding, they cannot be regulated to provide a constant output for electrical load and speed variations. MEGAMIC’s Active Rectifier Regulator converts the unregulated AC output of the PM Alternator to provide a constant DC output, irrespective of variations in the speed of the alternator or the loading conditions. The Regulator consists of two modules  Single-board Active Rectifier Controller  Active Rectifier Power Stack, customized for the Power rating of the Alternator
