POWER_SUPPLY_MONITOR

Published:2009/7/5 22:47:00 Author:May

Circuit Notes This circuit uses a tricolor LED display to indicate acceptable and unacceptable output voltages. One to set the upper voltage limit, the other, the lower voltage limit. When the monitored voltage is above the set maximum, the LED display turns red. Yellow turns on for voltages below the set minimum, and green turns on for voltages between the high and the low settings. The circuit does not need a separate power supply. It is powered by the voltage it monitors.The circuit can be adapted to monitor voltage differences between two power supplies. Should the monitored voltages differ by more than a set value, a visual or an audible alarm would warn the operator about the difference.The circuit can also be modified for remote monitoring and the use of a separate power supply.   (View)

HIGH_VOLTAGE_SUPPLY

Published:2009/7/5 21:44:00 Author:May

Circuit NotesA 6 V battery can provide 100-150 Vdc center-tapped at a high internal impedance (not dangerous though it can inflict an unpleasant jolt). A 6.3 V transformer is connected in reverse with a transistor used in a Hartley oscillator configuration. The frequency of operation may be controlled by varying the value of the 10 K ohm resistor. The 10 μF capacitor must have a working voltage of at least 250 Vdc.   (View)

SIMPLE_HIGH_VOLTAGE_SUPPLY

Published:2009/7/5 21:37:00 Author:May

Circuit NotesA light dimmer, a 1 μF capacitor and a 12 V car ignition coil form the simple line powered HV generator. The current in the dimmer is shown in Fig. B. At times t1, t2,..., set by the dimmer switch, the inner triac of the dimmer switches on, and a very high and very fast current pulse charges the capacitor through the primary of the induction coil. Then at a rate of 120 times per second for a 60 Hz line, a very high voltage pulse appears at the secondary of the coil. To obtain an HV dc output, use a voltage doubler. D1 and D2 are selenium rectifiers (TV 18 Siemens or ITT) used for the supply of television sets. High value output shock protection resistors, R, are recommended when suitable.   (View)

Single_chip_power_supply_with_linear_regulation

Published:2009/7/23 22:59:00 Author:Jessie

The HV-1205 converts ac into regulated dc to power low-voltage components, such as ICs. Input voltage is 120 V at frequencies from 48 to 380 Hz. Output voltage is set by selection of external components, as shown in the table of Fig. 7-6B, and it can be any value between 5 V and 24V, at 50 mA. Recommended values for components shown in Figs. 7-6C through 7-6G are as follows: fuse F1 is 1/4 A, 2AG; source resistor R1=150 Ω; snubber capacitor C1=0.05μF, ac rated; metal-oxide varistor (MOV, Fig. 7-6G) surge suppressor =V130LA20 or equivalent; pre-regulator capacitor C2 =470μF, with a voltage rating about 10-V greater than chosen VOUT; inhibit capacitor C3=150 pF for 50/60 Hz, and 47 pF for 400 Hz, with a voltage rating about 10-V greater than chosen VOUT; output filter capacitor C4=1μF minimum, 100μF reduced output spikes to about 25 mVp p-p; R2, RA, RB, and VZ=values shown in table Fig. 7-6B (VOUT adjustment). Note that the HV-1205 does not provide isolation from the line.   (View)

Figure 7-3 shows a MAX620 connected to form a complete stepper-motor drive. TTL/CMOS signals from the logic network are translated to high-side levels that drive four N-channel power MOSFETs, supplying current to each of four stepper-motor phases. The diodes provide a discharge current path for the stepper-motor windings. MAXIM NEW RELEASES DATA BOOk, 1992, P. 4-28.   (View)
