Connection of further loads
The connection of further loads (e.g. cabinet ventilation or climatisation) parallel to the
frequency inverter / power feedback unit at a common circuit breaker like in figure 2.6.5 is
not allowed. If it's done nevertheless, in case of tripping of the circuit breaker the connec-
tion to the network (energy sink and synchronising element for the power feedback unit)
misses. The IGBT's now switch the DC-voltage directly to the other loads. The resulting
nearly rectangular "net"-voltage drives a current through the loads, which level and form
depends on their impedance. Is the power consumption of the loads to small, the DC-
voltage and also the output voltage of the power feedback unit rises during the feedback
operation. This increased voltage may damage all connected components.
