VOLTAGE SENSING CIRCUITS AND METHODS FOR INVERTERS |
摘要 |
A voltage sensing circuit includes a voltage divider and a voltage rectifier. The voltage divider divides a first output voltage on a first output voltage line to a first divided output voltage. The voltage divider comprises a first metal foil and a first capacitor. The first metal foil and the first output voltage line can form a first capacitive component. The first capacitive component is coupled in series with the first capacitor. The first capacitive component and the first capacitor can generate the first divided output voltage. The voltage rectifier is coupled to the voltage divider and can rectify the first divided output voltage to a sensing voltage indicative of the first output voltage.
