The power MOSFET grid drive circuit is the 6-line integrated IC drive core IR2130 produced by IR Corp. In the IC, there are the over-current/voltage and low voltage protection, lock and indication circuit, so the users can conveniently use it to protect the power MOSFET under drive. IR2130 controls the 3 power tubes with the internal bootstrap technique. In the real system, the bootstrap capacitor reacts slowly, the system separator DC-DC provides with power for the circuit on the bridge arm power MOSFET.
