Full Form of SMPS

SMPS stands for switch mode power supply. An electronic power supply that uses a switching regulator to efficiently convert electrical energy. Also called switching power supply. This is a power supply unit (PSU) commonly used in computers to convert voltage to the computer's tolerance. This device contains live electronic components that efficiently convert electrical energy. Switching power supplies use superior power conversion technology to reduce overall power loss. GK Capsule Free pdf (download) https://www.safalta.com/static-general-knowledge-capsule

Like other power supplies, SMPSs transfer power from a DC or AC power supply (often a line power supply, see "power supply") to a DC load such as a PC, converting voltage and current characteristics. Unlike linear power supplies, the pass transistor in switching power supplies alternates between low-loss, full-on, and full-off states continuously, spending very little time in high-loss transitions and wasting minimal power. A hypothetical ideal switching power supply consumes no power.

Voltage regulation is achieved by varying the ratio of on-time to off-time (duty cycle). In contrast, a linear power supply regulates its output voltage by continually dissipating power in the pass transistor. A key advantage is the high electrical efficiency of switch-mode power supplies.

How does SMPS work?

SMPS devices regulate and regulate the output voltage using a switching regulator that turns the load current on and off. The average voltage between off and on will produce enough power for the device. Unlike linear power supplies, SMPS pass transistors switch between low-loss fully-on, and fully-off modes, significantly shortening power-hungry transition times and minimizing wasted power.

What are the advantages and disadvantages of SMPS?

The main advantage of switching mode power supplies is their high efficiency (up to 96%) compared to linear regulators, as the switching transistor consumes very little energy as a switch. Other benefits include smaller size due to heat generation equivalent to the elimination of bulky mains frequency converters, lower noise, and lighter weight. Standby power consumption is often much lower than transformers. Transformers in switching power supplies are also smaller than transformers at traditional power frequencies (50 Hz or 60 Hz, depending on your region), so they require cheaper raw materials such as copper.

Disadvantages include increased complexity, generation of high-amplitude radio-frequency energy that low-pass filters must block to avoid electromagnetic interference (EMI), and voltage ripple at the switching frequency and its harmonic frequencies. Very low-cost SMPS can couple electrical switching noise onto the mains power line and cause interference to devices connected in phase. A/V equipment. Non-power factor correcting SMPS also introduces harmonic distortion.
