TDK has been granted a United States patent for the control and monitoring of paralleled power supplies connected in a scalable master-slave configuration. This technology is used for its Genesys+ high voltage programmable power supplies.
The scalable master-slave technology allows up to thirty power supplies to be paralleled yet achieve a dynamic response and ripple and noise performance comparable to that of a single power supply. A simple parallel data link cable is connected between units, enabling the master and slave units to automatically configure and set their parameters accordingly. The master unit then becomes the single point for programming, measurement and status, including the display of the total current of all the paralleled units.
“This US patent recognises the years of hard work our Genesys+ engineering teams have put into developing this unique scalable master-slave technology,” said Doron Peled, Managing Director of TDK‑Lambda Israel. “The technical performance of the product is truly world-leading, enabling customers to optimise a wide range of demanding applications, and we are extremely pleased to now have the means to protect our intellectual property.”
The DSP-based family was launched by TDK three years ago and has expanded from 5kW 1U high models to encompass a full suite of 1.5kW to 15kW fully programmable power supplies. Output voltage and current combinations range from 0 10V to 0 600V and 0 2.6A to 0 1500A. All the models in the series are capable of operating in constant voltage, constant current and constant power modes.
Programming is standardised across the series via the front panel controls, remotely via LAN (LXI 1.5), USB 2.0 and RS232/485 communications, or by using the isolated analogue control and monitoring (0 5V, 0 10V), which are provided as standard.
Optional interfaces include a choice of GPIB (IEEE488.2) and the Anybus CompactCom interface platform for EtherCAT, Modbus-TCP and other interface options as they are released. Software drivers, a waveform creator and a virtual front panel GUI are provided in the
