Abstract

Extremely long distance control, hardly reachable actuator/target and costly network development  are some concerns within a distance control system. Such control is computer control for advertisements placed in tricky areas as locations over the bridge, at a junction, etc. The provider usually performs system inactivation in order to save energy. But until now, it is still difficult to find a system that can be turned on and off in remote manner. That is why the distant control using telephone can be the best alternative solution. Not only can the telephone be used in wide range of area, but also easily operated. The developed circuit in this research uses dual tone multiple frequency (DTMF). It is operated by pressing telephone button as control input for microcontroller. The microcontroller processes the input and controls the computer via relay and serial port. The result of experiment shows that the developed application is able to shut down and turn on computer as well as to apply software remotely.

Abstract

This developed cycloconverter circuit simulates grid connector circuit using two function generators, which substitute AC power. The first function generator was used to represent input wave from PLN with 50 Hz frequency. The other function generator was used to represent input wave from new generator with 10-90 Hz frequency. Such initial condition enabled us to control the frequency increase from 10Hz – 40Hz to 50Hz and decrease from 60Hz – 90Hz to 50Hz. This cycloconverter used trigger circuit to activate its electrical components. The trigger circuit contains trigger parts such as thyristor and MOSFET. All hardware components in this circuit were controlled by microcontroller ATMega 8535. This controller manages all trigger circuits that were needed by cycloconverter. The experiment result shows that the cycloconverter wasable to modify frequency and phase angle, so that it enabled the connection to the electrical grid.
