1. Project OverviewThis project involves the construction of the new Jakarta–Bandung High-Speed Railway, with a mainline length of 142.3 km, including 76.79 km of bridges (54.5%), 16.47 km of tunnels (11.69%), and 47.64 km of embankments (33.81%). Four stations—Halim, Karawang, Padalarang, and Tegal Luar—have been constructed. The Jakarta–Bandung HSR mainline is 142.3 km long, designed for a maximum speed of 350 km/h, with a double-track spacing of 4.6 m, including approximately 83.6 km of balla

As home energy storage evolves from "backup power" to "energy manager,"smart control appsare becoming the command center for households worldwide. More than a remote switch, it’s your intelligent brain for energy freedom and bill reduction—Scenario 1: Blackout? Zero-Second Switch, Safety at Your Fingertips A midnight storm knocks out grid power—your phone lights up: ‘Backup activated. 32-hour runtime secured.’With apps likeHi-Smart Energy(from Hi

In discussing the requirements for load resistance in DC voltage sources versus AC voltage sources, it's important to note that there isn't a universal rule stating that DC voltage sources always require low load resistance, while AC voltage sources always require high load resistance. The actual requirements depend on the specific application, circuit design, and the matching principles between the power source and the load. However, certain applications may favor particular ranges of load resi

What is an Uninterruptible Power Supply?Uninterruptible power supply definitionAn uninterruptible power supply is a device capable of providing a continuous power supply with the primary purpose of protecting critical loads from grid outages, voltage fluctuations, frequency changes, and other power quality issues.The basic components of uninterruptible power supply: Battery pack: provides backup power to the UPS. When the mains power fails, the battery pack can supply power to the load. Charger:

What is a UPS (Uninterruptible Power Supply)?AnUninterruptible Power Supply(UPS) is defined as a piece of electrical equipment which can be used as an immediate power source to the connected load when there is a failure in the main input power source.In a UPS, the energy is generally stored in flywheels, batteries, or super capacitors. When compared to other immediate power supply system, UPS have the advantage of immediate protection against the input power interruptions.It has very short on-ba

What is a Regulated Power Supply?A regulated power supply converts unregulated AC (Alternating Current) to a constant DC (Direct Current). A regulated power supply is used to ensure that the output remains constant even if the input changes.A regulated DC power supply is also known as a linear power supply, it is an embedded circuit and consists of various blocks.The regulated power supply will accept an AC input and give a constant DC output. The figure below shows the block diagram of a typica
