Inverter with frequency and voltage waveform generation

Inverter with frequency and voltage waveform generation

A three-phase electrical supply (L1,L2,L3) is connected to a diode bridge circuit and the output of this connects with a capacitive intermediate circuit (CDC). This operates with an a.c. inverter circuit (W) with transistors coupled to a control circuit (S) that has inputs from a frequency generator...

Zusammenfassung:A three-phase electrical supply (L1,L2,L3) is connected to a diode bridge circuit and the output of this connects with a capacitive intermediate circuit (CDC). This operates with an a.c. inverter circuit (W) with transistors coupled to a control circuit (S) that has inputs from a frequency generator circuit (D) and a power regulating circuit (P). The frequency generating stage is coupled to a changeover switch (U) that also connects with a variable clock frequency (Ft). A limiter circuit (B) connects with the frequency generator and the power regulator and responds to actual voltage and current.
