Latest Patents

One of his latest patents is a power converter that includes a positive bus ground. This innovative power converter can provide a power supply grounded on a positive electrode bus of a DC power supply without the need for an additional power supply, such as a switching regulator. This design not only reduces the circuit size but also lowers costs. When the switching device T1 of the upper arm is ON, the potential at point U is nearly equal to the potential at point P. Consequently, the current ic1 flows from the positive electrode of a first drive power supply into a capacitor to charge it. The power supply formed by this capacitor can be utilized as a power supply grounded on a positive electrode bus of the DC power supply.
