	COMPARISON OF THE FOLLOWING POWER COMPONENTS: BIPOLARMOS, MOSFETS, GTO THYRISTORS AND HYBRID DARLINGTON using a 60 amp, 240 volt DC chopper	[View]   [Download]

Abstract	The aim of the study is the comparison of these components from the practical point of view of the user: - The ease of paralleling is excellent for BIPOLARMOS, MOSFETS as well as for the transistors of the HYBRID DARLINGTON. It is well known that this is not the case with GTOs. - The residual voltage drop is, in general, of 2 or 3 volts, except for the "modified" HYBRID DARLINGTON (which can reach 0.33 V). - The MOSFETs need special radiator cooling (with water for example) to attain a reasonable residual voltage drop (2 or 3 V). - The GTOs need very carefully designed circuitry. - The MOS need a simple snubber. - The HYBRID DARLINGTON can be used without a snubber. - The latch up phenomenon of BIPOLARMOS does not occur if: the temperature is lower than 100°C, the fall time of the voltage Vds is sufficiently long (for example 10 us) and the gate pulses are sufficient (18 V for example).
