Accurate time-domain simulation of power electronic circuits✰
Electric Power Systems Research, 2021Abstract Modern power electronic circuits contain numerous switches driven by high frequency controllers and can cause discontinuities in time-domain simulation methods. This paper presents numerical problems resulting from discontinuities when simulating power electronic circuits. Limitations in existing methods are analyzed.

Power electronic circuit topology
Proceedings of the IEEE, 1988A generalized concept of 'sources' that embraces both power generators and power consumers is presented. This approach simplifies the basic topological aspects of power electronic converter circuits, which are reduced to an array of switches for selectively interconnecting two source systems.

Software breadboards for power electronic circuits
IEEE Transactions on Power Electronics, 1991A software breadboard is a means of simulating power electronic circuits at the device-level. The objective is to obtain detailed performance information such as device voltage and current waveforms and power dissipations. The intent is to accurately model the circuit for use in place of measurements to assess performance and even in a design mode to ...

Power electronic circuits and devices
2005This chapter reviews the main classes of circuits and devices that are currently used, emphasizing the basic operating principles and characteristics. The three-pulse rectifier supplies a resistive load in series with a filter inductor, the inductor being large enough to ensure that the load current is continuous and ripple-free.

Modeling of Power Electronics Circuits Using Wavelet Theory
Sampling Theory in Signal and Image Processing, 2007In this paper, wavelet based transient simulation is proposed for solving power electronics circuits. The wavelet domain equivalents of electrical circuit components are defined for solving the network to find currents and voltages of the nodes. During the computer simulations, a number of simulations are performed to obtain the best level of wavelet ...

Power Conditioning in Electronic Circuits
1989Principles of energy flux transmission, as described in the previous chapterf are applied to switckmode electronic circuits. An investigation is conducted into the role of “stray” and “parasitic” impedances during power conditioning at high frequencies, as means to gain insight into the optimisation of circuits operating at high power-frequency ratings.

Quadratic Power Conversion for Power Electronics: Principles and Circuits
IEEE Transactions on Circuits and Systems I: Regular Papers, 2012Quadratic converters have the voltage conversion ratios of two cascaded converters, but with fewer switches. They are not widely used, however, because they are generally less efficient than other converter types, but they can be useful for certain applications.

Integrated circuits for power electronics applications
2010 IEEE International Symposium on Industrial Electronics, 2010Integrated circuits are used more and more in power electronic applications in an attempt to reduce size and increase versatility and reliability. In 2006, the analog power ICs constitute about 38% of the $19B power management market. The power management market is one of the most dynamic sectors of the semiconductor industry, with around 13% yearly ...
