Using Multimeter to Test Electric Motors

Three-phase asynchronous motors are widely used. When electricians are repairing motors, they often encounter some old motors that lack nameplates or markings, or the nameplates and markings are unclear. How to use a multimeter to determine and test the motor windings, number of poles, speed, etc., is discussed below. 1. Determining the Start and End … Read more

DSP-Based T-Type Three-Phase PFC Charging Pile Solution

Abstract With the popularity of new energy vehicles, efficient and stable charging piles have become important supporting facilities. This paper proposes a DSP-based T-type three-phase Power Factor Correction (PFC) charging pile solution, supporting a DC output of 500-1000V, with a maximum current of 60A and an output power of 30KW. By adopting the T-type three-phase … Read more
