| Abstract |
B-SIT has an advantage that its on-resistance is
extremely low compared to those of other power
semiconductor switching devices. Accordingly, we can
suppress its conduction losses during large current
operation. Then, high conversion efficiency is expected when
B-SITs are utilized as the switching devices of high
frequency inverters. Here, we adopt newly developed BSITs
which have the maximum ratings 150V/50A and
prepare a breadboard of a conventional single-ended pushpull
(SEPP) high frequency inverter, which has a simplified
circuit constitution and relatively wide range applications.
This paper describes the characteristics of B-SIT on the
basis of the experimental results of the breadboard. Its
operational frequency is fixed at 50 kHz with PWM control
technique for output power regulation. Its load is induction
fluid heating systems for super-heated-steam production. |
