Abstract

This work proposes an additional function for a VSD (Variable Speed Drive) which sends and receives information over the power lines and simultaneously, implements the protection against insulation faults to earth. Using the magnetic components of the insulation fault protection system of the motor, the prototype injects and detects the communication signals over the power line. The system works on both communication schemes, with and without the PWM (Pulse Width Modulation) perturbation in the power lines, which are the two possible real applications. In order to set a proper communication between the motor and the drive, the communication channel was modeled and the noise was characterized. An FSK modulation and demodulation scheme was developed and tested. A 10 kbps communication over a 125 m length of cable and over a 1 km pi-section model of the same cable was successfully achieved with the laboratory prototype.

Abstract

This work presents several topologies of asymmetric high voltage converters for electrostatic particle accelerators. The options are compared on the basis of their transfer functions and the magnetic components required, and the most suitable for the intended purpose is selected. Simulations and measurement results of the prototype, which has symmetrical voltage output and soft switching in the main transistor, are presented. The prototype built features output voltages of 10 kVand-10 kV, the converter uses a single common command ground for the transistors simplifying its drivers, and also by means of the presented snubber circuit it recovers energy during soft switching.
