Latest Patents
Masashi Hamamoto holds a patent for an "Electric power conversion device and control circuit determining occurrence of an abnormality state." This device includes a transformer, a DC-AC conversion circuit, an AC-DC conversion circuit, and a control circuit. The control circuit calculates an input current instruction value (Iref) based on the difference value (ΔV) between the output voltage (Vout) of the AC-DC conversion circuit and an output voltage instruction value (Vref). A comparator is utilized to compare the input current (Iin) of the DC-AC conversion circuit with the value (Iref). The DC-AC conversion circuit is controlled based on the comparison result of the comparator. Furthermore, the control circuit accurately determines the occurrence of an abnormality state of the electric power conversion device based on the operation state of the comparator, the difference value (ΔV), and the input voltage (Vin) of the DC-AC conversion circuit without relying on any output current of the AC-DC conversion circuit.
