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.

ISLAMABAD (AP) — Former Pakistani Prime Minister Imran Khan was taken back to prison early Friday after a medical exam at a private hospital, the government said, following a Supreme Court order on his medical care.

Khan was taken from Adiala prison to Shifa International Hospital in Islamabad after midnight and examined by doctors before being returned to the prison, Information Minister Attaullah Tarar said.

“A team of qualified doctors, including an ophthalmologist, a cardiologist and a physician, conducted a detailed examination of him and declared him medically fit,” Tarar said in a post on X.

Tarar said Khan’s sister, Azma Khan, was present throughout the examination and treatment.

Khan’s Pakistan Tehreek-e-Insaf party, or PTI, had earlier confirmed that he was transferred to the hospital following a Supreme Court order earlier this week.

Khan’s party and family had demanded that he be allowed to remain at the hospital for treatment.

Earlier, a senior Cabinet minister said the government would comply with the Supreme Court order and could consider treatment abroad if adequate care was unavailable at a government facility.

The latest development comes a day after Parliamentary Affairs Minister Tariq Fazal Chaudhry said the government had approached the Supreme Court to seek clarification on whether the medical relief granted to Khan applied only to the former premier or could be extended to other prisoners.

Chaudhry's comments Thursday came two days after a three-judge Supreme Court panel ordered authorities to take Khan to Shifa International Hospital in Islamabad for a medical examination, following months of concerns from his family and personal physicians about his health and access to medical care. The court ordered that he be examined by a medical board that includes specialists and one of his personal physicians, Faisal Sultan.

Earlier Thursday, Chaudhry wrote on X that the government would fully comply with the Supreme Court’s ruling and that its request for clarification was not intended to defy or delay implementation of the decision. He later said all arrangements were in place to transfer Khan from prison to the hospital.

After midnight, local media reported that Khan — who has not been seen publicly since his imprisonment in 2023 in a graft case — was being examined at the hospital.

The government maintains that under existing rules, prisoners are provided medical treatment in prison and can be transferred to government hospitals when necessary.

Concerns about Khan’s health intensified in late January after his family said he had lost about 85% of the vision in his right eye, a claim the government disputed. Authorities later said Khan had regained about 70% of his vision in the eye and that his condition was improving.

The former cricket star turned politician was ousted in a parliamentary no-confidence vote in April 2022 and has been imprisoned since 2023 after being convicted in multiple cases.
