Mode 2
In this mode transistor gets turned off by the negative output of PWM current flows through inductance L diode D then divide into two parts one flows through capacitor C and other load. In this condition the magnetic field in the inductor collapses and induces a large voltage across the coil of opposable polarity.
That adds to the input voltage capacitor C will charge through this current and maintain the o/ p voltage when transistor gets turned on for next cycle.
Q. What is Stored Program Control ? Stored Program Control:Modern digital computers use stored programmed concept. Here, a program or a set of instructions to the computer is s
Q. What is meant by regulation? The output of most power supplies should be a constant voltage. Unfortunately, this is difficult to achieve. There are two factors that can caus
