Capacitor charging methods and apparatuses that use a secure parallel monitoring circuit |
摘要 |
A capacitor charging circuit and method including a plurality of serially connected capacitors and parallel monitor circuits connected in parallel on a one-to-one basis to the capacitors. Each one of parallel monitor circuits applies a direct-current source voltage to a capacitor and bypasses a charge current of the capacitor when the charge voltage of the capacitor exceeds a reference voltage. Each of the parallel monitor circuits includes a reference voltage circuit, a voltage detecting circuit, a comparator, a bypass switching circuit, and a voltage limiter. The reference voltage circuit generates the reference voltage. The voltage detecting circuit detects the charge voltage of the capacitor. The comparator compares the reference voltage with an output voltage from the voltage detecting circuit and controls the bypass switching circuit to bypass the charge voltage using the voltage limiter to limit a voltage applied to the bypass switching circuit.
