Latest Patents
One of Kanai's latest patents is a control apparatus for a power converter. This innovative device features a plurality of semiconductor switching devices that convert direct current (DC) power into alternating current (AC) power, outputting three levels of voltages. The control apparatus includes a command voltage generator that outputs a command voltage vector, an integrator that calculates a difference integral vector, and a difference vector calculator that determines difference vectors by subtracting the command voltage vector from possible output voltage vectors. Additionally, a vector selector is employed to choose the output voltage vector based on the largest angle with the difference integral vector, provided it exceeds a predetermined value. The gate signal generator then determines the switching states for the semiconductor devices based on the output voltage vector.
Another notable patent involves a gate circuit that includes a turn-off gate circuit. This circuit is composed of an OFF gate power source connected to the emitter of a semiconductor switching element, along with a switch that connects the other terminal of the OFF gate power source to the gate of the semiconductor switching element via a resistor. The gate circuit is enhanced with a second switch that connects the OFF gate power source directly to the gate of the semiconductor switching element, allowing for improved timing in the turn-off operation.
