Description

The LoPAC MI COTS family consists of three ultra low profile, fan-cooled, switching power supplies that combine the advantages of power factor correction (PFC) with high-power density. All units feature universal input and accept voltages from 85 – 264 VAC , 47 – 500 Hz, or 100 – 300 VDC (100 – 380 VDC for the PFC Mini). All LoPAC MI products feature a physically rugged design for COTS applications and have available options such as -40°C operation and conformal coating for demanding environments.

The PFC Mini consists of an off-line single phase, power-factor-corrected front end, EMI filter, cooling fan, customer interface, associated housekeeping circuits, and a selection of Vicor’s DC-DC converters. Input AC mains voltage is applied to a terminal block. The input current is passed through an EMI filter designed to meet conducted noise limit “B” specifications in FCC Part 15 and EN55022, Class B (with VI-200/VI-J00 Series modules. If Maxi, Mini Micro series modules are used, it meets FCC Class A and EN 55022 Class A. Certain configurations meet Class B).

At start-up, inrush current is limited by a PTC thermistor. The PTC is shunted out shortly after initial power-up by a DC bus voltage sense circuit driving a relay. After rectification, the input voltage is put through a boost converter that keeps the AC input current sinusoidal and synchronized with the input AC voltage (in compliance with EN61000-3-2). The boost converter delivers a regulated input to the hold-up capacitors and a high voltage backplane.

The backplane supplies power to the DC-DC converters that provide the desired low voltage regulated outputs.
