Power converter topologies for better traction drive packaging

A pseudo current source power converter topology comprising:

• an electric load;
• a pseudo current source to power the electric load formed from a voltage source, a first capacitor in parallel with the voltage source, and an inductor coupled in series with the voltage source and further in series with the first capacitor wherein the inductor operates to hold a current delivered to the electric load stiff but controllable;
• and
• a driver associated with the electric load having power electronics disposed therewithin to drive the electric load, wherein the power electronics has an associated first and a second switch and a second capacitor wherein when the first and second switches alternate between alternating open and closed positions and cooperate with the voltage source, the first capacitor, and the inductor to charge—the second capacitor.

A pseudo current source power converter topology comprising:

• a battery formed from a voltage source having first capacitor connected in parallel with the voltage source, wherein the battery is packed within an associated first package;
• an inductor coupled in series with the battery, wherein the inductor operates to hold a current delivered to an electric load constant, and wherein the inductor is in communication with the battery and is packaged within a second package;
• and
• combination electric load and driver associated with the electric load packaged within a third package, wherein the driver has power electronics disposed therewithin to drive the electric load, and wherein the power electronics has an associated first and second switch, and a second capacitor wherein when the first and second switches alternate between alternating open and closed positions and cooperate with the voltage source, the first capacitor and the inductor to charge—the second capacitor, wherein the electric load is packed within a third package in combination with the driver.
