What is PWM in smps?
PWM (Pulse Width Modulated) power supplies are a type of switching power supply. Pulse Width Modulation is generally used to help regulate the voltage in a switching power supply. This is necessary when the current demand on the power supply or the charging system’s supply voltage is not constant.
Why PWM is used in smps?
A switch-mode converter varies its dc output current in response to load changes. One widely-used approach is pulse width modulation (PWM) that controls the power switch output power by varying its ON and OFF times. The ratio of ON time to the switching period time is the duty cycle.

What is a switched mode power supply ( SMPS )?
A switched-mode power supply (SMPS) is an electronic circuit that converts the power using switching devices that are turned ON and OFF at high frequencies. The high efficiency of an SMPS makes them popular for use in computers and other sensitive electronics. A basic AC-DC SMPS consists of:

What happens when a PWM power converter fails?
Failure of the control IC can induce various power supply failure modes, from a reduction in regulation and/or response, to complete output failure. Protection within the IC invokes shutdown of all control signals, turning the module off. Figure 1 shows a simple diagram of a typical line switch-mode power converter.
