... voltages as delivered by the short distance sensors were digitally converted by a MAX1037 A/D converter and then forwarded to the I8052 microcontroller. Data was filtered against noise and sent to the main desktop computer through the serial connection. Figure 3. Tabletop prototype: installation of short-range sensors around the table (two sensors in ...

... circuit, figure 2, is effective in turn-off surge voltage and suitable for chopper circuit. It is also effective for oscillation by parasitic reactance and dv/dt noise. However, when it is applied in large capacity, IGBT resistance for the snubber must be set to low to dissipation heat. In very large capacity ...
