Claim 19:
20. An electronic system comprising:
a plurality of pairs of semiconductor switching elements; and
electronic circuitry corresponding to the plurality of pairs of semiconductor switching elements,
wherein the electronic circuitry includes
a detection circuit including a diode, a cathode side of the diode being connected to one end of a semiconductor switching element and an anode side of the diode being connected to a first node;
a comparator circuit configured to compare a voltage of the first node and a threshold voltage and generate a first signal;
a first filter configured to suppress the voltage of the first node in a first period based on a control signal indicating turn-on of the semiconductor switching element; and
a control circuit configured to determine at least one of the threshold voltage and the first period based on the first signal, and
an AC current is generated from a DC voltage by successively switching the pair of the semiconductor switching elements to be simultaneously turned on for at least a partial period of time.
