Abstract: A magnetic cooling apparatus including a plurality of magnetic regenerators including a plurality of magnetocaloric materials to emit heat when magnetized and to absorb heat when demagnetized. The magnetic regenerators are rotatably disposed on a circumference having a predetermined radius, at least one coil is disposed on the circumference and coupled to the magnetic regenerators, and a plurality of permanent magnets is provided inside and outside the circumference to generate a magnetic field to magnetize or demagnetize the magnetic regenerators. The at least one coil interacts with the magnetic field generated by the permanent magnets to rotate the magnetic regenerators. The coil interacting with the magnetic field to magnetize or demagnetize the magnetic regenerators is coupled to the magnetic regenerators such that the magnetic regenerators reciprocate or rotate, thereby minimizing a size of the magnetic cooling apparatus, relative to the use of a motor. In addition, a member to switch a channel of a heat transfer fluid directly performs heat transfer between the heat transfer fluid and an external fluid, thereby minimizing heat loss.

Abstract: The present disclosure relates generally to a switch driving circuit and power factor correction circuit having the same, and more particularly, to a technology to provide a negative offset using Zener diodes to prevent malfunctions in driving a switch. The switch driving circuit to operate a switch implemented with a Field Effect Transistor (FET) includes a first Zener diode connected to a control input end of the switch; a capacitor connected in parallel with the first Zener diode; and second and third Zener diodes for providing a negative offset to fix a voltage applied between the gate and source of the switch to a negative value.
