Daanaa Announces Real-time Programmable, Ultra-high Voltage Conversion Ratio Power Converter

VANCOUVER, British Columbia--(BUSINESS WIRE)--Apr 10, 2025--

Daanaa Resolution, Inc., an innovator in power system architecture and design, announces its Power Transaction Unit (PTU), a novel approach to ultra-high voltage conversion ratio power converters that is real-time programmable. In a compact module, the PTU provides greater than 95% power conversion efficiency across a one-decade operating range, with a voltage conversion ratio exceeding 110x. The PTU is bidirectional, multimodal (AC/DC), with dynamically adjustable output amplitude and phase. It enables Original Equipment Manufacturers (OEMs) in automotive, solar energy, high-performance computing, and other industries to develop highly energy-efficient systems with reduced engineering and operational overhead.

The rising demand for electricity, driven by homes, businesses, AI, and vehicle electrification, makes efficient energy conversion critical. However, renewable energy sources, such as solar cells and batteries, generate low-voltage DC outputs (often less than 4V), while most applications require stable high-voltage AC (240V) or DC (12V–800V). Traditional power conversion techniques rely on multi-stage architectures and serialized energy sources, leading to inefficiencies, compounding losses, cascading failures, and increased system complexity.

Unlike traditional multi-stage systems, Daanaa’s PTU enables parallel connections for greater resilience while minimizing losses. Its real-time programmability adapts to changing conditions like sunlight and environmental conditions, battery state of charge (SOC), battery state of health (SOH), ensuring stable, optimized power transfer. By integrating multiple power functions into a compact, single-step module, Daanaa improves efficiency, simplifies system design and reduces engineering, operational, and maintenance costs.

Key Benefits

"We’re receiving growing interest from unconventional solar and energy storage applications struggling with efficiency," said Udi Daon, Daanaa’s CEO. "We’re offering a hands-on experience with our development system for Building-Integrated Photovoltaics (BIPV), Vehicle-Integrated Photovoltaics (VIPV), Energy Storage Systems (ESS) and more."

PTU Development System Available for Evaluation

Customers can evaluate the PTU’s capabilities using Daanaa’s development system, which connects to photovoltaic modules and batteries to demonstrate the technology’s potential in solar and energy storage applications.

BIPV and VIPV face challenges in optimizing solar energy generation due to irregular surfaces, dynamic shading, and complex power electronics. The PTU’s short-cell substring approach adapts to irregular surfaces, while per-substring DC optimization and ultra-fast MPPT maximize energy harvest even in dynamic shade conditions. Real-time configuration enables dynamic control of the output to a load.

The PTU also enhances battery performance. In electrified vehicles, it increases range by 10%, boosts motor power by over 40% and reduces charge time by over 50% without modifying battery cell count.

The development system includes an enclosed module featuring input and output connectors for easy integration with sources, loads, and measurement devices. It supports low-voltage DC input of 3V–6.7V and outputs either 380V-800V DC or 240VAC based on configurable settings.

WASHINGTON (AP) — President Donald Trump said Tuesday he is ordering a blockade of all “sanctioned oil tankers” into Venezuela, ramping up pressure on the country’s authoritarian leader Nicolás Maduro in a move that seemed designed to put a tighter chokehold on the South American country's economy.

Trump's escalation comes after U.S. forces last week seized an oil tanker off Venezuela’s coast, an unusual move that followed a buildup of military forces in the region. In a post on social media Tuesday night announcing the blockade, Trump alleged Venezuela was using oil to fund drug trafficking and other crimes and vowed to continue the military buildup until the country gave the U.S. oil, land and assets, though it was not clear why he felt the U.S. had a claim.

“Venezuela is completely surrounded by the largest Armada ever assembled in the History of South America,” Trump said in a post on his social media platform. “It will only get bigger, and the shock to them will be like nothing they have ever seen before — Until such time as they return to the United States of America all of the Oil, Land, and other Assets that they previously stole from us.”

Pentagon officials referred all questions about the post to the White House.

The buildup has been accompanied by a series of military strikes on boats in international waters in the Caribbean and eastern Pacific. The campaign, which has drawn bipartisan scrutiny among U.S. lawmakers, has killed at least 95 people in 25 known strikes on vessels.

The Trump administration has defended it as a success, saying it has prevented drugs from reaching American shores, and they pushed back on concerns that it is stretching the bounds of lawful warfare.

The Trump administration has said the campaign is about stopping drugs headed to the U.S., but Trump’s chief of staff Susie Wiles appeared to confirm in a Vanity Fair interview published Tuesday that the campaign is part of a push to oust Maduro.

Wiles said Trump “wants to keep on blowing boats up until Maduro cries uncle.”

Tuesday night's announcement seemed to have a similar aim.

Venezuela, which has the world’s largest proven oil reserves and produces about 1 million barrels a day, has long relied on oil revenue as a lifeblood of its economy.

Since the Trump administration began imposing oil sanctions on Venezuela in 2017, Maduro’s government has relied on a shadowy fleet of unflagged tankers to smuggle crude into global supply chains.

The state-owned oil company Petróleos de Venezuela S.A., commonly known as PDVSA, has been locked out of global oil markets by U.S. sanctions. It sells most of its exports at a steep discount in the black market in China.

Francisco Monaldi, a Venezuelan oil expert at Rice University in Houston, said about 850,000 barrels of the 1 million daily production is exported. Of that, he said, 80% goes to China, 15% to 17% goes to the U.S. through Chevron Corp., and the remainder goes to Cuba.

It wasn't immediately clear how the U.S. planned to enact what Trump called a “TOTAL AND COMPLETE BLOCKADE OF ALL SANCTIONED OIL TANKERS going into, and out of, Venezuela.”

But the U.S. Navy has 11 ships, including an aircraft carrier and several amphibious assault ships, in the region.

Those ships carry a wide complement of aircraft, including helicopters and V-22 Ospreys. Additionally, the Navy has been operating a handful of P-8 Poseidon maritime patrol aircraft in the region.

All told, those assets provide the military a significant ability to monitor marine traffic coming in and out of the country.
