Latest Patents

Higashiyama's latest patents include a snubber circuit and a power conversion system utilizing the same. The first patent describes a snubber circuit that incorporates a clamp circuit and a voltage conversion circuit. This design is intended to absorb electrical energy from a main circuit, effectively clamping the secondary-side voltage. The main circuit is of an insulating type, designed for electric power conversion. The voltage conversion circuit is also insulating and connects to primary-side voltage points, converting direct-current voltage generated by the clamp circuit.

The second patent outlines a snubber circuit and power conversion system that manages voltage levels between first and second voltage points in a main circuit. When the voltage exceeds a specified clamp value, the first clamp circuit absorbs energy to maintain the voltage. Conversely, if the voltage falls below a second clamp value, the second clamp circuit injects energy to stabilize the voltage. This innovative approach to voltage management enhances the efficiency of power conversion systems.
