ABSTRACT
This chapter focuses on developing current controllers rather than voltage controllers. It explains the designs of linear controllers, sliding mode controllers for a power factor corrected (PFC) and bidirectional converter. Wind and solar power generation, which are both environmentally friendly and economically competitive, have become a popular option for electricity power generation. The power circuit and its control configuration for the PFC boost converter are realized with a two-cascade control structure. For fuel cell vehicle applications, the DC-bus voltage needs to be boosted to increase the motor power density lowering the motor current for the same traction power. A typical brushless DC (BLDC) motor drive system consists of the BLDC motor, power inverter, and digital controller. The voltage source inverter is connected to the DC bus. The digital controller energizes each phase of the BLDC motor in a sequence synchronizing with the rotor position in order to produce constant torque.
