F-SEM 2014 H Bridge Application Note 5! MOSFET Selection When selecting MOSFETs for an H Bridge application there are several criteria that are important to consider. In the context of a high power inverter one of the most important pieces of information is the Drain-to-Source resistance of the device.
The H-bridge arrangement is generally used to reverse the polarity/direction of the motor, but can also be used to 'brake' the motor, where the motor comes to a sudden stop, as the motor's terminals are shorted, or to let the motor 'free run' to a stop, as the motor is effectively disconnected from the circuit. An H-Bridge is used to control the direction of the motor and to also provide enough current for the motor to run. Operation: 1. To force a motor to switch in two directions, one requires a minimum of 4 switching elements. We will use 4 MOSFET to control the direction of the motor. Consider Figure 2 shown below.
