During a ground fault of the high voltage circuit, the freewheeling diode in an OESS charger creates a fault path between the energy storage elements ... J Krause,J Mcphee - Asme Joint Rail Conference: Jrc 被引量: 0发表: 2017年
If the hold current target IHOLD is reached, the high-side driver is switched off and the current recirculates through the diode connected to ground for a fixed time (tHOLD_OFF). The high-side driver is switched on again, and the cycle repeats until the STARTx pin goes low or the ...
