Linear mode Power Supplier provide an ideal DC source to your DUT with high stability
TRP, TDP and TIP series are a basic design models for a power supply which consists of a linear device such as a transistor or MOSFET in series with a rectifier and load.
Many engineers who have experienced serious prob-lems caused by ripple and noise from SMPS still want to use linear mode Power Supplier under low efficiency and big size.
It’s very hard to reduce the size of a linear mode power supply because an irreducible big power trans-former should be employed.
But we can try to increase efficiency of a linear mode power supply with simple changes.
Most of loss power is dissipated at the series linear device that is working as a variable resistor to maintain a stable DC output without ripple and noise.
To minimize the power loss of a linear mode power supply, the phase controlled SCR method for a rectifier that maintains a low voltage drop across the series linear device has been used.
Also many parallel MOSFETs with current sharing circuit that have low static drain-source on-resistance have been employed instead of transistors.
It will reduce the voltage drop across MOS-FET in series.
Linear mode Power Supplier usually are the simplest, most effective solution for providing bench power because they provide sufficient power with stable regulation and little noise.
