1. Overview
The IRADK31 Reference Design Kit (Figure 1) is an electronic controller for driving a 1/3HP
(see Table 1) 3-phase Motor from either a single phase 120VAC or 230VAC. The circuit
provides all the necessary functions, including software driven High performance Micro
Controller, for starting and operating the motor. It also includes an AC on/off switch, EMI
filter and the rectification stage with a buck-converter system that provides the auxiliary
+15V and +5V supply. This controller is software driven through a Graphical User Interface
(GUI) that enables the user to control the entire electrical system and motor parameters. In
addition, it allows the user to monitor the DC Bus current, motor speed, and detects fault
conditions.
2. Features
• Fused 120/230VAC input.
• AC input on/off switch and EMI filter.
• NTC inrush current limiter
• 3-Phase, variable voltage output.
• Opto-isolated RS-232 serial link interface to the Graphic User Interface software.
