    While voltage measurement can be done easily with the help of an isolation transformer, a more effective method is to utilize a differential probe for high-voltage measurements. Differential probes are equipped with two inputs and are specifically designed to measure the voltage difference between these inputs.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

    How Is SMPS Different From Normal Power Supply<\/h3><\/div><\/div>\n\n\n\n
    \n

    An SMPS distinguishes itself from a linear power supply by its method of converting the primary AC voltage into the output DC voltage. Instead of relying on a linear approach, the SMPS employs a power transistor to generate a high-frequency voltage that is subsequently passed through a compact transformer and filtered to eliminate any AC noise.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

    \n

    Which Device Is Used in SMPS<\/h3><\/div><\/div>\n\n\n\n
    \n

    In SMPS, the inverter utilizes the PWM technique. The inverter’s output is then converted to dc through the use of a diode rectifier. Since the inverter operates at a high frequency, the ripples on the dc output voltage can be easily filtered out using small filter components.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

    \n

    Which Switch Is Used in SMPS<\/h3><\/div><\/div>\n\n\n\n
    \n

    Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power), to DC loads, such as a personal computer, while converting voltage and current characteristics. It utilizes a high-frequency switching converter that converts DC to DC.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"
