发明名称 APPARATUSES AND METHODS FOR DETECTING OVER VOLTAGE AND/OR UNDER VOLTAGE
摘要 An apparatus for detecting over voltage and/or under voltage can include: a reference voltage receiving unit configured to receive a reference voltage; a gradient measuring unit configured to measure a gradient value of a voltage waveform of the reference voltage; and a pulse conversion unit configured to convert the gradient value into a first pulse width and store it. Further, the apparatus can include: an electrical power receiving unit configured to receive an input voltage from an external power source; and a voltage detection unit configured to compare the first pulse width with a second pulse width to detect an over voltage condition or an under voltage condition.

主权项 1. An apparatus for detecting over voltage and/or under voltage in an electronic/electrical device, the apparatus comprising: a reference voltage receiving unit configured to receive a reference voltage; a gradient measuring unit configured to measure a gradient value at a point in a waveform of the reference voltage; a pulse conversion unit configured to convert the gradient value obtained from the gradient measuring unit into a first pulse width corresponding to the gradient value; an electrical power receiving unit configured to receive an input voltage from an external power source; and a voltage detection unit configured to compare the first pulse width with a second pulse width corresponding to the input voltage to detect an over voltage condition or an under voltage condition.
