POWER CONVERSION APPARATUS AND POWER CONVERSION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18308926 titled 'POWER CONVERSION APPARATUS AND POWER CONVERSION SYSTEM

Simplified Explanation

The patent application describes a power conversion apparatus that converts electric power from an input terminal to an output terminal.

• The power conversion circuit in the apparatus includes a sensor that generates a detection signal based on the output voltage or current.
• A signal generation circuit generates a second detection signal based on the first detection signal.
• The control circuit is responsible for controlling the operation of the power conversion circuit.
• The signal generation circuit consists of a corrector, a photocoupler, and an output circuit.
• The corrector performs correction processing on the first detection signal.
• The photocoupler has a light receiving device that generates a light reception signal.
• The output circuit outputs the second detection signal based on the light reception signal.
• The corrector adjusts the correction processing based on the current transfer ratio of the photocoupler.

Original Abstract Submitted

A power conversion apparatus includes an input power terminal, an output power terminal, a power conversion circuit, a signal generation circuit, and a control circuit. The power conversion circuit converts supplied electric power and outputs the converted electric power. The power conversion circuit includes a sensor that generates a first detection signal corresponding to an output voltage or an output current. The signal generation circuit generates a second detection signal corresponding to the first detection signal. The control circuit controls operation of the power conversion circuit. The signal generation circuit includes a corrector, a photocoupler, and an output circuit. The corrector performs correction processing on the first detection signal. The photocoupler includes a light receiving device generating a light reception signal. The output circuit outputs the second detection signal corresponding to the light reception signal. The corrector performs the correction processing corresponding to a current transfer ratio of the photocoupler.
