ABSTRACT:
A current limiter of a voltage/frequency type inverter which comprises a comparator for comparing an output current to an applied reference value to generate a current comparator output signal; a delay circuit, coupled to the comparator, for delaying the timing of the current comparator output signal for a predetermined time duration to generate a current limiting signal based on the result of the comparison; and a pulse output circuit for outputting a predetermined pulse based on the current limiting signal.
