HIGH EFFICIENCY DC/DC CONVERTER

designs built to your specifications

Applications

This unit is meant to accompany 32V S-band LDMOS high power RF power amplifier.  Converts 220-240VAC mains power to 32V 30A.

Configurations

Transformer isolated high power regulated switching power supply for high power RF amplifiers. Over-current protected with inrush limiting and soft start.

Key Features

•    Transformer isolation
•    Efficient, isolated full H-bridge switched power supply
•    200kHz switching frequency minimizes inductor sizes
•    Current limiting, overcurrent protection (circuit breaker) with inrush limiting and soft start
•    Heavy-duty input and output filtering for noise immunity and low EMI
•    3V LVTTL/CMOS enable for automatic power-up sequencing using microcontroller

Options

Full bridge rectifier on secondary. Option for active (switched) rectifier for higher efficiency if needed.  Other input/output voltage combinations are available to suit application.
