A closed-loop cooling system is internal to the enclosure of an induction drive system. Two inverter modules of the induction drive system each includes three insulated gate bipolar transistor (IGBT) modules for producing an AC output from a DC source, the AC output received by an induction coil for heating a metal.

High power switching devices for inductive heating applications

A power inverter comprises a plurality of high power switching modules that form an alternating current (AC) output; a plurality of terminals in communication with the high power switching modules for outputting the AC output; a capacitor bank that provides a conditioned voltage to the high power switching modules for producing the AC output in response to receiving and storing electrical energy related to a direct current (DC) supply; and a case positioned over the high power switching modules. The capacitor bank is mounted to the case, and the capacitor bank is positioned over the high power switching modules so that the high power switching terminals are proximal the capacitor bank for reducing inductance. A gate driver module at a top region of the high power switching modules includes a plurality of planar transformers for reducing a distance between the capacitor bank and the gate driver.

Power converter

A scooterboard, including a board supported on a front and rear skate wheel trucks, and wherein the front skate wheel truck is alternatively unlocked or locked by means of a selectively lockable swivelling assembly so as to be free swivelling or stationary, and further including a removable steering post and a removable steering column carried by the scooterboard to allow an operator to select different steering embodiments thereof.
