introduction of Power MOSFET was originally regarded as a major threat to the power bipolar transistor. However‚ initial claims of infinite current gain for the power MOSFETs were diluted by the need to design the gate drive circuit capable of supplying the charging and discharging current of the device input capacitance. This is especially true in high frequency circuits where the power MOSFET is particularly valuable due to its inherently high switching speed. On the other hand‚ MOSFETs have a higher on

The Design of DC Motor Driver for Solar Tracking Applications Abstract - Solar trackers rely on a direct-current (DC) motor driver circuit to control the movement of the solar panel. However‚ conventional DC motor drivers used in solar tracking system do not provide any options for speed and torque control. Hence‚ the fixed speed of the DC motor leads to either too fast or too slow tracking movement. Usually‚ the output torque is set to the maximum. If the load (solar panels’ weight) is small
