Vicor powermoduler gør Hollywood filmproduktioner mere energivenlige
Firmaet ReVolt har udviklet en bedre måde at drive filmset og studier på ved at levere en ren, mobil og 'always on' forsyning, der er opbygget med powermoduler fra Vicor (in english).
Vicor, a leading high-density power solutions provider, is enabling big changes amongst Hollywood. Most production companies today rely on noisy, environmentally harmful gasoline and diesel generators to operate their movie sets. But as these become more elaborate - with enormous footprints and an expanding array of specialized electronics - energy demands have escalated, as have unwanted levels of dangerous CO2 emissions.
Vicor customer, ReVolt Holdings, Inc. (ReVolt), has developed a better way to power movie sets and studio backlots by providing clean, mobile, always-on electricity. ReVolt systems power everything - from cameras, sound and lighting equipment to special effects rigs and basecamps - quietly, efficiently and with no CO2 output. Founded in 2020, the startup is quickly gaining traction, partnering with the likes of Amazon MGM Studios, Apple Studios, Sony Pictures, Warner Bros. Discovery and its subsidiary HBO, to power their sets.
A single 10kW diesel generator emits about 75dB of noise- roughly the same as a leaf blower - and produces as much CO2 in 12 hours as a gas car travelling 225 miles. Because of their sound and exhaust fumes, diesel power sources are typically installed 1,000 feet or more from the set location, which requires thousands of feet of costly, cumbersome cables.
Diesel generators also produce 'dirty' power that requires extra filtration when used in sensitive digital lighting and motion control equipment. ReVolt charging systems produce a pure sine wave profile that ensures a clean, stable power source. And they are nearly silent, emitting noise akin to a computer fan.
ReVolt designed its uninterrupted power technology into an expanding fleet of portable vehicles. The smallest, the WeVolt, generates 17.5kWh capacity and 14kW output - equivalent to a small house generator. The 8,500 pound Mule delivers 210kWh of capacity and 120kW of output power, supplying on-demand energy across 480V, 208V, 240V and 110V connections.
Vicor power-dense modules ensure reliability, performance and efficiency
To ensure stable voltage levels, ReVolt adopted Vicor BCM bus converters, DCM DC-DC converters, and most recently, PRM regulators.
The BCM4414 converts and isolates 800V into a 48V at 35A bus, which the DCM3414 taps off to regulate 24V loads. The 770W/in3 BCM4414 (4.35 x 1.4 x 0.37in) also serves as a battery emulator, reducing the need for a conventional and bulky 48V battery. The PRM is a non-isolated buck-boost DC-DC regulator capable of converting 48V into various output voltages, with power density exceeding 2kW/in³ and 96% efficiency.
- With one Vicor module, we can do what it would take six or eight components to achieve, says J.D Schwalm, CEO, ReVolt.
