Power electronics design verification

Designing power converter involves a great deal of testing, both during design and production phases. This typically means balancing conflicting design goals. A key consideration is usually efficiency, but compliance to different standards is also essential. Another important aspect is safety, as testing must sometimes be carried out using hazardous voltages have to be performed, which calls for safe means of taking measurements.

To overcome these challenges, Rohde & Schwarz offers products and solutions for all phases of converter development from design phase up to compliance and production test.

Accurate verification of power supply startup sequences for auxiliary bias supplies

An offline AC/DC switching converter has no separate bias power supply that provides power to the control integrated circuit itself. Here, an auxiliary primary winding and discrete components are added to supply power to the control circuit. Verifying this circuitry is essential and requires accurate and detailed signal level and timing measurements. The startup sequence takes a long time, which needs to be taken into consideration in the measurement and requires an instrument with sufficient memory.

Safe debugging of embedded power supplies with isolated channels

Safety is a prime concern when measuring at high voltages. A power converter often has integrated microprocessors that control it, and debugging often means paying attention to both safety and power conversion at the same time. This application card describes how to ensure both requirements are met with Rohde & Schwarz oscilloscopes featuring isolated channels.

Conducted emission limits

Most of today's electronic devices draw non sinusoidal current. This gives rise to harmonic currents injected back into the public supply system. These need to be checked on all devices with the CE marking. The R&S®HMC8015 Power Analyzer offers automated testing of limits for harmonic current emissions.

Inrush current measurement

All electronic devices contain capacitive or inductive components that can cause a disproportionately high current while switching on the device. To properly assess these inrush currents, Rohde & Schwarz offers a solution with seamless acquisition and real-time signal processing as well as a high dynamic range.
