What is a diode & a transistor for reverse battery protection?
To provide these electronic safeguards, manufacturers typically chose either a diode or transistor for reverse battery protection. The simplest protection against reverse battery protection is a diode in series with the battery, as seen in Figure 1. Figure 1. Diode in Series With Battery
What is inverter protection circuit?
Fig. 1. An inverter protection circuit. In motor drive applications, the inverters are usually protected only from overloading conditions, using either intrusive current sensing techniques, which measure the DC input current or the load current , , or special motor control algorithm techniques , , .
What is a reverse polarization protection scheme?
When a system receives power from a battery that has the potential to become reverse-polarized, such as in automotive motor-driver applications, protection schemes are required that prevent reverse voltage from being applied to system components such as the gate driver, MOSFET bridge, and motor combination.
What is the simplest protection against reverse battery protection?
The simplest protection against reverse battery protection is a diode in series with the battery, as seen in Figure 1. Figure 1. Diode in Series With Battery In Figure 1, the diode becomes forward biased and the load’s normal operating current flows through the diode.
What voltage polarity reversal does a storage battery use?
Many self-contained critical electronic systems and subsystems, especially in automotive applications, use a 12 V or 48 V storage battery for the primary power source. To prevent extensive damage during operational life, these systems require the design-in of systems that—at a certain voltage level—provide protection from voltage polarity reversal.
How can I restore power to a 12 volt inverter?
To restore power to a 12 volt inverter, first ensure that any short circuit or overload condition is removed from the inverter side. Then, disconnect the 12 V battery input to reset the inverter.
