power supply circuit การใช้

• One common cause is feedback through the plate power supply circuit.
• A flyback converter is a power supply circuit operating on similar principles.
• Most of these used a transformerless power supply circuit.
• An example of this kind of use would be a DC error amplifier used in a regulated power supply circuit feedback loop system.
• Upon completion of pre-charging, the pre-charge resistance is switched out of the power supply circuit and returns to a low impedance power source for normal mode.
• Also, when flyback transformers fail, they frequently will also damage the horizontal output transistor that drives the flyback transformer, and sometimes even blow fuses in the low voltage power supply circuits.
• The original DIN 45596 phantom-power specification called for a maximum of 2 mA . This practice has carried forward to the present; many 48-volt phantom power supply circuits, especially in low-cost and portable equipment, simply cannot supply more than 1 or 2 mA total without breaking down.
