HIGH SPEED, HIGH VOLTAGE (HV) CAPACITOR SYSTEM (HVCS) CONTROL SYSTEMS AND RELATED METHODS FOR HVCS CHARGE/DISCHARGE UPON ACTIVATION/DEACTIVATION OF A HV MAIN POWER SYSTEM (MPS) OR SYSTEM FAULT EVENT INCLUDING A FIRST AND SECOND TIMING SEQUENCE FOR MPS MAIN RELAY(S) AND HVCS RELAY(S) OPERATION

摘要

Exemplary apparatuses and methods are provided which provide a safety system that automatically controls charge and discharge of high voltage (HV) capacitors upon application or removal of HV power to a HV system (e.g., a surveillance radar) that includes different timing and sequencing for turn-on/turn operations. In one embodiment, an apparatus and method automatically discharges high voltage (HV) capacitors when HV power is deactivated. Another aspect of an embodiment of the invention automatically deactivates a HV capacitor shunt when the HV system's main HV power is applied or activated. Additionally, an exemplary apparatus requires no human interaction when shunting the HV capacitors, increasing electrical system safety.

1. A power control system comprising:
a high voltage (HV) system comprising one or more HV capacitors, a HV main power system (MPS), and a first MPS user input section comprising a first user MPS input and second user MPS input section, said first user MPS input section is configured to generate a MPS activation signal and said second user MPS input section is configured to generate a MPS deactivation signal, said MPS comprising a first power relay system configured to selectively supply power to said HV system and charge said one or more HV capacitors upon receiving a first relay activation signal; and a HV capacitor discharge/charge control system (HVCDCCS) comprising a first and second section configured to send said first relay activation signal to said MPS; wherein said HVDCCS first section comprises one or more second relays comprising one or more HV capacitor shunt relays configured to selectively couple said one or more HV capacitors to a power dump circuit adapted to remove stored electrical energy from said one or more HV capacitors, wherein said second relays are configured to couple said one or more HV capacitors to said power dump circuit until a second relay activation signal is received by each of said second relays, wherein said second relays decouple said HV capacitors from said power dump circuit upon receiving said second relay activation signal; wherein said HVDCCS second section comprises a crowbar control circuit (CCC) section comprising a timing control section configured to control said one or more first and second power relay systems in a first CCC operation and a second CCC operation, wherein said first CCC operation is based on a first CCC timing control sequence logic and said second CCC operation is based on a second CCC timing control sequence logic; wherein said CCC is configured to execute said first CCC operation upon receiving said MPS activation signal that triggers said timing control section to output said second relay activation signal to said one or more second relays within a first time period then said timing control section outputs said first relay activation signal to said power relay system after said first time period; wherein said CCC is configured to execute said second CCC operation upon receiving said MPS deactivation signal that triggers said timing control section to output a first relay deactivation signal to said first power relay system in a second time period then said timing control section outputs a second relay deactivation signal after said second time period.
