SMPS

9. IN SMPS INSTEAD OF MAKING THE
SERIES PASS TRANSISTOR CONDUCTING
CONTINOUSLY A TRANSISTOR IS
OPERATED IN SWITCHING MODE THAT
ACTS AS A RAPIDLY OPENING AND
CLOSING SWITCH. PRACTICALLY WHEN
TRANSISTOR IS OPERATED AS A SWITCH
IT DISSIPATE VERY SMALL POWER
BASIC PRINCIPLE

10. (A)LOW POWER DISSSIPATION
RESULTS I LESS HEATING.
(B)BETTER REGULATION AND
EFFICIENCY.
(C)SMALL IN SIZE AND LOW
COST POWER SUPPLY
ADVANTAGE S OF SMPS

11. IT HAS MAXIMUM ADVANTAGES AS
MENTIONED EARLIER ONLY TWO
INHERENT DISADVANTAGES
( a ) SINCE IT USES SPIKING TECHNIQUE
IT GENERATES ELECTROMAGNETIC
INTERFERENCE (EMI) LIKE NOISE
SPIKES, WHICH MAY AFFECT AUDIO
SECTION OF THE MAIN CIRCUIT
( b ) THE CONTROL PART OF THE CIRCUIT
IS EXPENSIVE,COMPLICATED AND
LESS RELIABLE
DISADVANTAGES OF
SMPS
