Method and apparatus for control of pulsed power in hybrid energy storage module

A system, comprising:

• a flywheel;
• a first dynamo-electric machine directly coupled to the flywheel, the first dynamo-electric machine having (i) multiple input stator windings configured to accept power, (ii) a rotor winding configured to be excited by both a direct current (DC) and an alternating current (AC), exciter, and (iii) at least one polyphase output stator winding configured to deliver electric power at a first rate to a DC bus at different power, duty-cycle, and voltage levels;
• an array of active front end (AFE) and load resonant converters (LRCs) coupled to the input stator windings of the first dynamo-electric machine and configured to provide variable-voltage variable-frequency power from a power source to the input stator windings of the first dynamo-electric machine;
• an electro-chemical battery coupled to the DC bus and configured to exchange electrical energy in a bi-directional manner;
• a second dynamo-electric machine coupled to the flywheel and the first dynamo-electric machine by a shaft, the second dynamo-electric machine having (i) a controllable input stator winding and (ii) a plurality of polyphase output stator windings each coupled to a DC output;
• and
• a polyphase boost exciter configured to derive energy from the DC bus and excite the input stator winding of the second dynamo-electric machin, wherein the second dynamo-electric machine is configured to be excited at a second rate that is faster than the first rate;
• wherein the system is configured to bi-directionally transfer energy between the DC output, the electro-chemical battery, the flywheel, and the power source.
