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

A method for operating a power controls system comprising:

• providing said 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 section 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 HVCDCCS 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 one or more 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 one or more second relays, wherein said one or more second relays decouple said one or more HV capacitors from said power dump circuit upon receiving said second relay activation signal;
• wherein said HVCDCCS second section comprises a crowbar control circuit (CCC) section comprising a timing control section configured to control said first and one or more 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 first 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 input 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;
• operating said first MPS user input section to send said MPS activation signal, said CCC intercepts said MPS activation signal;
• commencing said first time period upon receiving said MPS activation signal;
• outputting said second relay activation signal to said one or more second relays from said CCC within said first time period;
• opening said one or more second relays upon receiving said second relay activation signal;
• outputting said first relay activation signal to said first power relay system from said CCC after said first time period has elapsed;
• closing said first power relay system upon receiving said first relay activation signal;
• activating said MPS upon closing said first power relay system;
• charging said one or more HV capacitors upon activating said MPS;
• operating said second MPS user input system to send said MPS deactivation signal, said CCC receives said MPS deactivation signal;
• commencing said second time period upon intercepting said MPS deactivation signal;
• outputting said first relay deactivation signal to said first power relay system from said CCC within said second time period;
• opening said first power relay system upon receiving said first relay deactivation signal;
• deactivating said MPS upon opening said first power relay system;
• outputting said second relay deactivation signal to said one or more second relays from said CCC after said second time period has elapsed;
• closing said second relays upon receiving said second relay deactivation signal;
• and discharging said one or more HV capacitors upon closing said second relays.
