Variable Transformer with capacitance multiplier -> DC bench
With this circuit you can''t really have a nice bench supply style current limit that doesn''t risk burning out the transistors since the variable transformer can''t automatically be made to track the current limited output voltage. But you could have fold-back limiting, where the output just completely collapses when there''s an overcurrent.

The Design And Construction Of Valve Mains Transformers
The earliest electrolytic capacitors were restricted in value, being typically 8 μ F – 16 μ F, then later, as much as 32 μ F. Nowadays values of say 47 μ F at 450 V working can be easily sourced, but, as was the case for the smaller values, there is still an advantage to be had by adding a series choke to reduce the HT ripple, see Design and Construction of Low Frequency Chokes

Transformers, Phase Converters and VFD
There are two common "flavors" of small bench grinders for 120V. One type has a switch that you can hear "click" as the grinder slows down. Those may have a start capacitor, or they may not. The other type has a capacitor, but no switch. The capacitor is always connected, and functions as both a start and a run capacitor.
6 FAQs about [Bench Transformer Capacitor]
What is a bench power supply?
A bench power supply is a power source to supply a specified direct current (DC) or DC voltage to a device under test (DUT) for observing the latter's behavior. Engineers and do-it-yourself (DIY) hobbyists frequently use bench power supplies when designing, testing, and debugging circuits and devices.
How to step down input voltage in a bench supply?
One of the basic circuit to step down input voltage is to use a buck converter topology. Some power supplies reduce input voltage using non isolated type while others use isolated type (example use toroidal, EI transformer). If I am designing a bench supply, which should I prefer? Buck converter is one of the example topology from SMPS list.
How opamp controlled bench power supply circuit works?
The working procedure of the opamp controlled bench power supply circuit is fairly basic uncomplicated, since regulated power supplies can be simply as particular forms of feedback amplifier. In this concept, the R1 and R2 generate a refernce sample signal from the output supply, which is by another reference voltage created by D2.
How to choose a transformer secondary voltage for a power supply?
Input high voltage AC going into a transformer which usually steps down the high voltage AC from mains to low voltage AC required for our application.For designing the Power Supply,the transformer secondary voltage is selected by considering the the output voltage of the power supply, losses in the diode bridge and the linear regulator.
What is a 10uf capacitor in a power supply?
A 10uF capacitor across the output terminals helps to reduce the AC impedance of the power supply. Q2 along with the resistors R8 and R9 constitute the current control circuit stage which enables a constant current output. Resistors R8 and R9 determine the output current limit, or simply the constant current value.
What happens if a bench power supply is 15 volts?
For example if the load is a 3.3 V LED, and input supply to the bench power supply is 15 V, then the output voltage has to be lowered to 3.3 V which is 15 - 3.3 = 11.7 V less. And this difference is converted to heat by the transistor, which could mean a efficiency loss of more than 70%.
