Power management

Hello I would like to get guidance on the design of MCU based 3 phase and single phase voltage monitoring(read energies, phase and line voltage, power factor, frequencies)

Using STM32F103C8T6 and Current transformers(A input) onboard current transformers

L6599 or L6699 as Full Bridge controller?

Hi,I am already using the L6599 as a HB LLC controller and I am trying to achieve higher output powers, however my input supply voltage is only ~30V. Already primary side currents are high. In order to bring these to realistic levels I really should ...

L6480 when in run mode I changed direction of the motor. But when its effected after a delay near to 750 ms what may be the reson. When I am trying with another motor with another settings the delay is reduced. Can any one explain the cause ?

What could cause the output of an LD1117 Voltage Regulator to increase above its specification?

My design is using an LD1117S33CTR voltage regulator. I am experience some rather odd behaviour where the regulators output is actually increasing from the expected 3.3V all the way up to 4V. What could cause such behaviour? I am stumped.

Problem with pin status after power on

Hi, I am solving the backlight of the display, which is controlled by a pin, but the problem is the state between power on and initialization, when the display flashes before the pin is initialized. This happens with both positive and negative contro...

Hi, what's the frequency range of EVALMASTERGAN5 demonstration board? gaston

STSPIN32F0,Vreg12(Pin6) cannot output DC voltage stably.

Problem Description.After reflow soldering the circuit board, after visual inspection to exclude the problem of soldering quality, the power test on the tooling (DC 12V power supply, the output of the circuit board is not connected to the load). Outp...
