H-Bridge Bootstrapping

Bootstrapping is a crucial aspect that you will find in all H-bridge or full bridge networks with N-channel mosfets. It is a process in which the gate/source terminals of the high side mosfets are switched with a voltage that’s at least 10V higher than its drain voltage. Meaning, if the drain voltage is 100V, then … Read moreH-Bridge Bootstrapping

Capacitor Inductor Calculations

Inductors can be imagined as the opposite of capacitors. The main difference between a capacitor and an inductor is that a capacitor carries a protective dielectric between its plates, which inhibits the conduction of current across its terminals. Here it acts like an open circuit. On the other hand the inductance of an inductor is … Read moreCapacitor Inductor Calculations
