Aachen 1989 Absmf. The paper discuses, with particular reference to the gate-drive circuit, the design of an inverter to reproduce a stored current
waveform with a hgh degree of accuracy for use in a motor drive system. The gate-drive bines low cost with individual over-
current protection for each switch, thus providing shoot-through and short-circuit protection without the need or expense of a link
choke. In addition to the gate-drive circuit design, the reasons for choosing MOSFETs as the main power devices, alternative gate-drive
circuit confiations and inverter protection techniques are discussed. Although designed for a standard bridge configuration, MOSFET
inverter, the gate-drivc circuit presented is applicable to other MOS input devices and to other power circuit configurations.
