In the realm of DC/DC power modules, the trend has been away from specialization and toward a “generalist” strategy. This means that the power modules no longer require a singular distinguishing feature for use in a specific application but rather have a variety of features that make them desirable for a wide range of applications. Timur Uludag, senior technical marketing manager at Würth Elektronik, looks at the individual requirements and gives an overview of how a DC/DC power module can fulfill the main requirements.
Monolithic?GaN ?integration has matured to the point that complex circuits like a half-bridge gate driver with various features, such as cross-conduction protection, can now be realized. These complete circuits are packaged into a single and simple-to-use component. This issue will also cover DC-to-DC and BLDC motor drive application examples that benefit from monolithic half-bridge integration.
SiC E-Fuse Board for Electric Vehicles
By Maurizio Di Paolo Emilio
The high-voltage electrical subsystems of battery electric vehicles (BEVs) and hybrid cars require a method to protect the high-voltage distribution and loads. Microchip Technology unveiled the E-Fuse demonstrator board, powered by SiC.
Real-Time Variable Gate Drive Maximizes EV Traction Inverter Efficiency
By Sonu Daryanani
The traction inverter in an electric vehicle is what forms the interface between the battery system and the power traction drive motor. The gate driver controls the switching of the high-voltage (HV) power devices, typically either silicon IGBTs or SiC MOSFETs.
Designing an LLC Resonant Converter for Audio Applications with High Peak Loads
By Giovanni Di Maria
For designers, power-conversion design in the audio field is a real technical challenge, as peak loads could be much higher than the root-mean-square (RMS) power requirement. They must strike an optimal balance between thermal requirements, size and weight of the solution, cost and, of course, efficiency.
Compensating for the Impact of EMI Filter X-Capacitance on the Power Factor of Active PFC
By Andy Smith
Modern switch-mode power supplies use a combination of X- and Y-capacitors with inductors to filter common- and differential-mode EMI. The filter element sits in front of any active (or passive) power-factor–correction (PFC) circuit (Figure 1), so any distortion on the power factor (PF) imposed by the reactance of the EMI filter will alter even a perfectly corrected voltage-current relationship.
