A high-speed semiconductor switch is operated after syncing sequence time data sent via an optical link from a PC with output from a short-circuit generator. The PC creates, changes and manages sequence time data as well as displays sequence timing charts and waveforms imported from a digital oscilloscope.
Use: Used in high-power testing laboratories, as well as for controlling power devices and measurement devices when carrying out input, short-circuit and interruption tests on high-voltage large-capacity switching devices.
Programming language: Visual Basic and C
Controls the power output of a power generator to a resolution of one phase degree for up to 100 external devices in sync with the output of a short-circuit generator. In order to achieve this CEW developed a high-speed semiconductor switch. The specifications are as follows;
Operating speed: 3 µsec or less
Switching capacity: AC110V 10A
The operating time for each external device is set by a sequence setting PC and transmitted to the sequence timer board via an optical link. The sequence setting is displayed as a graph on the software screen enabling the operating time to be set by drag and drop operations of a mouse.
