A DC POWER SOURCE FOR A HIGH VOLTAGE POWER APPARATUS |
摘要 |
A dc power source for a high voltage power apparatus, the dc power source including one or more strings including a plurality of dc power source units connected in series, and switches configured to connect and disconnect said strings. The switches are solid-state switches distributed among the power source units of each string, and all solid-state switches in the string are arranged so that they are turned on and off simultaneously. Each switch is connected in parallel with a first controllable semiconductor in a first direction and connected in parallel with a second controllable semiconductor in a second direction which is opposite to the first direction, and the dc power source includes a control unit configured to bypass a failed switch by triggering the forward biased of the first or second controllable semiconductor connected to the failed switch in case a fault in the switch is detected. |
