    Is it good idea to resistor divide a 1kV voltage ?

    Hello all, I need to run a 12V/0.6A dc fan to cool the MOSFETs of an inverter with 1kV input. it would be overkill to use some power supply to step down the 1kV to 12V or any DCtoDC converter!.. I thought of using just a resistor divider to step down the voltage to an acceptable range to use a...

    Power supply for Single Peltier Module

    Hi Experts, I've got 12V, 20A, 240W SMPS (AC to DC) Power supply, & I've attached single(1) Peltier Module (TEC- 12706) - 12V, 6A(Max) with that SMPS But when I gave power to Peltier Module without Heat Sink via SMPS (Power Supply), it works for few seconds & then it stopped (Heating &...

    Help understanding heat pipes parameters

    I need help understanding heat pipes parameters. Let's say I need to transfer heat from the heating component on the PCB to the heat sink. For this I want to use a heat pipe. To calculate the final temperature on the PCB component, I use thermal resistances. But there is no such parameter for...

    LM2567 Switching Regulator - Heat Sink required...?

    Hello I am making a power supply to power a Raspberry Pi/camera/touch screen (5V @3A), and some LEDs, servos/motors (12V LEDs and 9V servos/motors). I am using a 12V/5A adapter to supply power, and an LM2576 switching regulator to take the 12V down to 5V @3A for the pi etc. and a 7809 to drop...
