AC/DC Power Supply

Mains offline AC/DC bespoke power supply design, providing three dedicated custom outputs.  This unit was used in an MPEG satellite decoder and modulator.

Turbine scavenge fan controller

An advanced controller for the monitoring and controlling of a scavenge fan used in a turbine. Using ruggedised power electronics to control the 400Hz supply, fault currents of up to 50A are monitored and controlled. This design incorporates an advanced micro-controller that continuously checks for the safe operation of both the unit and fan, then relays information to the management system.

Power supply and monitor for high reliability applications


This design has an advanced high density power supply and monitoring system for ultra high reliability environments. Special PSU topology provides high efficiency and power factor correction. Four micro-controllers provide a high level of monitoring and a built in management system provides advanced communications and in-unit intelligence. The unit is designed for shock, vibration and impact testing.
 

6 Watt 4 output DC/DC converter
(extended temperature range and low profile )

Using ferrite materials (Philips 3F3 ) it is possible to run PWM convertors at increasingly higher operating frequencies and power densities.

This design includes a wide range 24 volt (nominal) input with 4 isolated outputs. The unit is unusual in that one of the outputs is referenced to the primary side. Current mode control, ultra low impedance capacitors, schottky diode and FET technology combine to provide a robust solution to this particular low profile, industrial temperature range power requirement.
