Can SMPS have multiple outputs?
Abstract: Personal Computers (PC) and embedded system based control applications require power supplies with multiple outputs delivering stiffly regulated and isolated DC voltages at different levels such as ±5 V, +3.3 V and ± 12 V.
How does an LLC converter work?
A regular LLC resonant half bridge converter works a combination mode of a voltage divider and amplifier of resonant inductor voltage of the resonant tank. At the resonant frequency, impedance of resonant tank is zero, which means the input voltage is 100% applied on the load.
Why does an LLC need a resonant converter?
The LLC resonant converter is the most suitable topology for designing switch mode power supply with stable output voltage [1]. It is able to regulate the output over wide line and load variations with a relatively small variation of switching frequency.
What is multi output power supply?
AC/DC multi-output Power supplies are standard models that are manufactured in volume and offer the most cost-effective option when multiple voltages are required. They come in Open Frame or Enclosed / Vented case in dual, triple or multi-output and are aimed at Original Equipment Manufacturers ( OEM ).
What is full bridge LLC?
ABSTRACT A full-bridge LLC resonant converter with series-parallel connected transformers for an onboard battery charger of electric vehicles is proposed, which can realize zero voltage switching turn-on of power switches and zero current switching turn-off of rectifier diodes.
What is LLC resonant controller?
The LLC converter is a resonant inverter with three reactive elements where the DC input voltage is turned into a square wave by a switch…
How do I connect two power supplies in series?
Two or more power supplies can be connected to supply higher voltages or current. The simplest method to create higher voltage is to connect the power supplies in series, set each supply to output the same voltage and each supply should have the same current limit.
What is full bridge LLC resonant converter?
Can I connect two SMPS in series or parallel?
SMPS can be used in series configuration mainly for achieving a level of voltage or power not available with a single standard unit. In theory any 2 or more power supplies can be connected in series, independently of their output voltages.
How is LLC taxed?
An LLC is typically treated as a pass-through entity for federal income tax purposes. This means that the LLC itself doesn’t pay taxes on business income. The members of the LLC pay taxes on their share of the LLC’s profits. State or local governments might levy additional LLC taxes.
