Configurable intelligent high power system

The configurable intelligent high power system, the iHP series, from Artesyn is designed for a range of medical and industrial applications. The modular power system is said to provide either a programmable voltage or current source; up to 24kW in 3kW increments; and can be configured for up to eight outputs using a variety of plug-in modules.

The series meet safety approvals which eliminate the need for an isolation transformer in medical equipment. The iHP power system also has industrial safety approvals and meets the SEMI F47 voltage sag tolerance standard for semiconductor processing equipment.

According to the company, the system offers developers either an analogue or digital interface to their system, supporting standard communications protocols, including CANbus, Ethernet and RS485. Digital control enables the use of the PowerPro software graphical user interface (GUI) to control and monitor all functions on one or multiple iHP systems. The PowerPro GUI also incorporates graphical script creation that allows users to write their own process control routines.

The system offers power factor correction (PFC) and low total harmonic distortion over a range of loads. It uses a multi-phase continuous mode boost PFC architecture, resulting in ripple current cancellation. The user can configure the iHP system for single- or three-phase input.

Users can configure the outputs as voltage or current sources and customise them to their exact applications requirements from a range of standard modules provided by Artesyn. These modules can be connected in series or parallel, while achieving accurate voltage and current sharing.

For specific types of loads and applications, the iHP series can be programmed to three different compensation configurations including resistive load, capacitive load and LED load.
