      The MOSFET bank is also known as the H-Bridge for a 3-phase motor. The H-Bridge is the circuit that converts the DC voltage to the 3-Phase AC voltage which is needed to spin the motor of the MSU solar car. The conversion takes place by having six MOSFETs in a specific way shown in Figure 3.3.

      When looking for a pump, select a mechanically-sealed end-suction unit with 3 phase motor. A pump-motor unit makes it possible to avoid a belt drive, reduces energy losses, is easier to install, costs less, and lasts longer than a system with a belt drive. Most pumps, even for powers of less than 1 kW, are supplied with three-phase induction ...
