Latest Patents
Kiyoshi Itani holds a patent for an inverter apparatus. This invention comprises a bridge circuit made up of a combination of multiple switching transistors, along with a microprocessor that controls the operation of these transistors. The apparatus utilizes pulse width modulation (PWM) theory to store patterns of ON and OFF states in a first ROM of the microprocessor. The transition patterns for electrical angles ranging from 0 degrees to 30 degrees are stored in a second ROM, while the timing data for each pattern is kept in a third ROM. The microprocessor manages the holding time data and outputs the ON/OFF pattern, effectively controlling the switching transistors. This cycle produces a continuous switching signal, allowing for an AC output via the PWM system.
