An H-bridge is one very useful circuit arrangement which lets us reverse the polarity across a load, so now with one DC supply we can make current flow through the load in both directions alternately. Because of that, these H-bridge circuits get used in many places like DC to AC inverter circuits, transformer drivers, bidirectional […]

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 […]
P-Channel MOSFET in H-Bridge Applications
Implementing P-channel MOSFETs in an H-bridge circuit may look easy and enticing, however it may require some stringent calculations and parameters for achieving an optimal response. P-channel MOSFETs are usually implemented for load ON/OFF switching. The ease-of-use of P-channel options on the high side allows them to be very convenient for applications like Low-Voltage Drives […]
6 Simple AC Bridge Circuits Explained
An AC bridge is a circuit which can be used for measuring parameters like capacitance, resistance, Inductance using differential method, by comparing them with known values of similar components, positioned diagonally across a bridge circuit, and through an analogue meter placed at the center of the bridge. Before we begin talking about the AC bridge […]
How Load Conducts in Half-Bridge Driver Circuits like IR2184 or IR2110
Many folks, especially beginners, they get fully confused when they try to use a half-bridge driver circuits using ICs like IR2184 or IR2110. They look at the datasheet diagram and start thinking, “Bro, how the load will conduct? The MOSFETs are switching one by one so how the current will pass through the load? Looks […]
Half-Bridge Mosfet Driver IC IRS2153(1)D Datasheet
In this post I have explained the datasheet, specifications, pinout configurations and a few application circuit for the IC IRS2153 which is a half-bridge IC from Texas Instruments. The unique feature of this half bridge driver is that it does not have to depend on external logic sources for the operations, rather allows configuring its […]
