1. Introduction

This application note describes the features and functions of Intronics

power’s AC100 series of open frame, Isolated AC-DC Converters.

These are highly efficient, reliable and compact, high power density,

single output AC/DC converters. Ultra-high efficiency operation is

achieved through the use of synchronous rectification and drive control

techniques. The modules are fully protected against short circuit and

over-voltage conditions. Intronics power’s world class automated

manufacturing methods, together with an extensive testing and

qualification program; ensure that all AC100 series converters are

extremely reliable.

3. General Description

A block diagram of the AC100 series converter is shown in Figure 1.

Extremely high efficiency power conversion is achieved through the use

of synchronous rectification and drive techniques. Essentially, the

powerful AC100 series topology is based on an isolated synchronous

forward converter. The control loop is optimized for unconditional

stability, fast transient response and a very tight line and load

regulation. The output voltage can be adjusted from +5% to –5%, using

a variable resistor.
