Functional description

T01036en.fm
The machine is run with single phase current, and is a combination of
an internal vibrator and a frequency converter.
The converter in the inverter rectifies the input voltage.
The direct voltage is converted in the d.c.-a.c. converter into 3-phase
alternating current (rotary current) and the frequency increased from
50/60 Hz to 200 Hz.
The d.c.-a.c. converter works in "pulse width modulation" mode which
generates a sinusoidal output current as an average, which ensures
the error-free operation of the connected machines.
The soft start of the connected machines permits the full utilization of
the output capacity of the inverter.
The actuation of the rectifier and inverter is carried out by a control
electronics with microprocessor.
