Title: Hiroshi Ogawa: Innovator in Feedback Circuits and Power Conversion
Introduction
Hiroshi Ogawa is a notable inventor based in Hamamatsu, Japan. He has made significant contributions to the fields of feedback circuits and power conversion. With a total of 3 patents to his name, Ogawa's work reflects his innovative spirit and technical expertise.
Latest Patents
One of Ogawa's latest patents is a feedback circuit designed to reduce various adverse effects caused by a low-pass filter while suppressing oscillations. This circuit includes at least one operational amplifier with a low-pass filter in its output portion. The design features a first feedback circuit portion that negatively feeds a signal from the input terminal of the low-pass filter back to the inverted input terminal of the operational amplifier. Additionally, a second feedback circuit portion is included, which also negatively feeds a signal from the output terminal of the low-pass filter back to the inverted input terminal of the operational amplifier. This innovative structure enhances the performance of the feedback circuit.
Another significant patent is the push-pull switching power converter. This converter consists of a series circuit that includes a first switching device, a primary winding of a first transformer, a primary winding of a second transformer, and a second switching device. The design also incorporates two capacitors and a partial path for current resonance. The voltage resonance in this converter causes the switching voltage waveform to resemble a sine wave, while the current resonance results in a sine wave for the combined current of the primary winding currents of both transformers.
