3.2 An electric motor drive system is made up of five main components. Figure 3.1 shows a block diagram of an electric motor drive. The input to the drive is the power source. The power source is the energy for the system. Next is the power electronic converter. The electronic converter manipulates the voltage, current, […]
3.1 The power diode is the simplest, uncontrollable power electronic switch. A power diode is forward biased (on) when its current is positive and reverse biased (off) when its voltage is negative. A thyristor is a controllable three-terminal device. If a current pulse is applied to its gate, the thyristor can be turned on and […]
