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.
Q. The no-load and blocked-rotor tests conducted on a 110-V, single-phase induction motor yield the following data: • No-load test: input voltage 110 V, input current 3.7 A, and
