Mode1
When the positive pulse from PWM is applied to the transistor Q shown in figure it gets turned on. In this condition current flows through transistor Q and.
Inductor L. Inductor stores the energy. Diode D is reverse biases in mode 2. If the transistor Q is supplied with negative pulse it gets turned off and inductor reverses its polarity. Now diode D is forward biased with negative polarity of inductor.
Voltage and Frequency Control Methods In this control method the ratio of voltage to frequency is kept constant so that the flux remains constant. The voltage at varia
