The Switcher is a patented electric vehicle controller technology which provides an efficient and inexpensive alternative to conventional controllers.
Using optimal algorithms to control the dynamic switching of ultracapacitor/battery modules into the power circuit,
the invention replaces expensive and fragile power electronics with robust inexpensive components.
The result is an electric vehicle which is far simpler and more reliable and durable, as well as more efficient.
No power electronics are used. Instead of the kilohertz frequency switching of conventional PWM controllers,
the Switcher uses very low frequencies.
The Switcher is so efficient that no cooling is required for any of its components,
There are no fans, no water pumps.
Optional ultracapacitors are used in a pulsed mode, delivering high power to the motor while at the same time
shielding the batteries from large current discharge rates and extending their lifespan.
Developed in New Zealand, the Switcher technology is protected by United States patent US8386102B2.
