“…To ensure high power efficiency of the modern AC rolling stock, various technical means providing optimum values of all three above-stated parameters are used. Such means are systems with active bootstraps [7,8], four-quadrant transducers [9,10], reactive power compensators [11,12]. The most widespread is the use of four-quadrant transducers (4qs transducers), as those that do not require additional transducers and have high power characteristics.…”

“…The detailed design and operating principles of 4qs transducers are given in [9,10,[13][14][15][16][17]. In [9,13], theoretical principles of construction are considered, calculation schemes and mathematical description of processes in the transducer are given, and the test simulation of the transducer in the traction and regenerative braking mode is performed.…”

“…From the control point of view, it is somehow easy to illustrate that v dc has certain influence on the input current harmonic of the 4QC. Double closed-loop control is commonly used for the 4QC of EMUs [19,20]. In the outer voltage loop of the control system, a proportional-integral (PI) controller is used to regulate the deviation between the reference value and the actual one of the DC-link voltage [21].…”

“…The four-quadrant converter (4QC) has the advantages of high power factor, low harmonic current and high regenerative braking performance, which has caused wide attention [1,2,3]. It is widely used in the field of unit factor rectification, industrial DC power supply, AC drives and so on.…”
