Variable Frequency Pulse-Width Modulation with FPGA for Power Converters

FPGA-based power converter control implementation In power electronics, advanced power converter control techniques often require that part of the converter ontrol algorithms are implemented on FPGA. With imperix converter controllers, this is made easy since FPGA-based control implementation is possible with both software development kits. In this regard, this paper presents a hardware implementation for hybrid neutral point clamped converters (HANPCs) using an FPGA for carrying out the modulation of a system. An FPGA possesses fast performance and high control flexibility by providing a reconfigurable computing speed.

FPGA-based PWM modulator for power converter control

Pulse width modulation (PWM) has been widely used in power converter control. Most high power level converters operate at switching frequencies up to 500 kHz, while operating frequencies in excess of 1 MHz at high power levels can be achieved using the planar transformer technology. The contribution of this paper is the development of a high-frequency PWM Digital pulse width modulators (DPWMs) have become an integral part of almost all embedded systems. It has been widely accepted as control technique in electronic appliances. One of the applications of DPWM lies in power electronics for controlling power converters (DC/DC, DC/AC, etc.). PWM operations are extensively used in the power converters.

Conventional switching power converters have high switching loss along with voltage and current stress because of the use of hard-switching pulse width modulation (PWM) control.

Regarding the second factor, resolution is limited mainly by the analog-to digital converter (ADC) and the pulse-width-modulation (PWM). However, the ADC resolution is becoming a less important problem, thanks to the windowed ADC technique [3] and because the PWM resolution needs to be higher than the ADC resolution for avoiding limit cycling. Also, a fast responding motor, advanced converter topology, and intelligent control technologies are necessary for steer-by-wire and brake-by-wire applications. Additionally, integrating actuators with devices (like power electronics components) increases the system efficiency and reliability, while lowering costs, space, etc.

This paper describes a combined Pulse Width Modulation (PWM)-Pulse Frequency Modulation (PFM) technique implemented in a Field Programmable Gate Array (FPGA) to control DC-DC converters. This technique changes the mode of operation from PWM to PFM with the change in the load condition. The efficiency of the proposed technique is determined by implementing a In particular, several PWM modulators are provided to fulfill the needs of the most demanding applications, whether it is for a traditional carrier-based or a more advanced multi-level modulator. Each individual block can be parametrized using an easy-to-use configuration dialog. Consequently, these modulators can be incorporated in constant switching frequency SMPS to enhance regulation capabilities but will result in limited improvement when integrated in resonant topology-based power-supplies.
