Multiplex voltage measurement apparatus |
摘要 |
A multiplex voltage measurement apparatus includes: (N+1) voltage detection terminals connected to N serially connected voltage sources; a capacitor which is charged with a voltage value of any of the N voltage sources; a first sample switch for selectively connecting odd-numbered voltage detection terminals among the (N+1) voltage detection terminals to a first terminal of the capacitor; a second sample switch for selectively connecting even-numbered voltage detection terminals among the (N+1) voltage detection terminals to a second terminal of the capacitor; a voltage measurement circuit for measuring the voltage value stored in the capacitor; a third sample switch for connecting the first terminal and the second terminal of the capacitor to the voltage measurement circuit; and a polarity controller for controlling the first and second sample switches such that one of the N voltage sources is selected while the third sample switch is open.
