76. y for the specified type of power supplies An overview of all available protections as well as a brief description of their behavior is presented in the following sections 32 12 OVC OVerCurrent The OVC check hardware software is performed on each module DC Link input current from the corresponding A3667 bulk and protects from short circuit conditions that could arise in the output stage section This protection is obtained from a Schmitt triggered signal fed by an opportunely conditioned Hall sensor that directly disables the output stage bridge driver The signal is also fed to the FPGA that disables the output power stage of the A3660BS in case an over current condition arises The acting of the over current protection generates a FAULT condition on the power supply status register and should be reset before re enabling the output 32 1 3 CB CrowBar The A3660BS module protection against output over voltage conditions is guaranteed by a crowbar protection circuit that as in the case of the over current protection one has a double level of reliability 1 e both hardware and software This protection is hardware activated when the output voltage crosses the threshold of VCB threshold 28 5 V This threshold value on the output voltage can be exceeded in situations where a large ZD value is generated by the energy stored in a large reactive load The crowbar circuit also guarantees dissipation of the residual ene
