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.
Mesh analysis procedure : 1. Assign a distinct current to every closed loop of the network. 2. Apply KVL around every closed loop of the network. 3. Solve the resulting
Q. What is the significance of source gate cutoff voltage? The source gate cutoff voltage is also called pinch off voltage. It is obtained when VDS increases and approaches a l
if load is removed so which motor will run fast? series or shunt?
Analogue Threshold switching a) Include a variable potential divider to the schematic diagram to control the transistor base voltage b) Include the potential divider compon
Equivalent Circuit of a Synchronous Machine A review of the material about elementary synchronous machines is very helpful at this stage to recall the principles of operation f
Since a controlled source acts at its terminals in the same manner as does an independent source, source conversion and application of KCL and KVL relations are treated identically
'Electric drives' is a term used to describe DC and AC electric motors that provide continuous rotarmotion. They are often controlled by 'electronic drivesystems' designed to contr
Q. Show a block diagram of a 4-bit, parallel-input shift-right register and briefly explain its operation.
Methods of Testing Irrespective of reasons, testing is commonly carried out 1. On site, or 2. In a Meter Testing Station (MTS) accredited as per IS/ISO/IEC 17025.
Q. For the low-pass filter configuration of Figure, with R i = R f = 1M, calculate C f such that the 3-dB point is at 1 kHz.
