| Description: | This work addresses the design of a circuit to minimize the adverse effects of MOSFET switching in a half-bridge configuration. MOSFETs suffer from efficiency and stability issues due to parasitic capacitances and inductances. To mitigate these effects, gate-on and gate-off resistors were added, along with a capacitor between the gate and source. These modifications proved effective in simulations and experimental tests, reducing disturbances and voltage spikes while improving system stability. The proposed solution enhances the performance of MOSFETs in high-frequency and high-power applications, increasing energy efficiency and reducing component stress. |
