“…Subsequently, a standardization gap existed for the frequency range of 2-150 kHz. As a consequence, electronic products have been designed that satisfy harmonic emission limits at lower frequencies (< 2 kHz) but instead have increased emission in the frequency range of 2-150 kHz [10]. As the number of reported complaints increase, efforts are redirected by standardization bodies to develop compatibility, emission, and immunity levels for this frequency range of 2-150 kHz.…”

Transient overvoltages are normal. Insulation must withstand not only the functional voltage, but also the transient overvoltages. A scheme called "insulation coordination" has been instituted by the International Electrical Commission to promulgate and standardize on coordinating the transient overvoltage suppression with insulation electric strength. This paper addresses the insulation requirements of the scheme.

The focus of this paper is on a simple half-bridge converter that performs power factor correction (PFC) using current sensorless control. Current sensors increase cost, auxiliary power required, conduction losses, and volume of the PFC converter. Moreover, measurement of high frequency current is demanding, especially in cost-sensitive applications. The PFC converter proposed combines simple half-bridge topology and improved current sensorless-control algorithm that takes into account conduction losses. These losses influence volt-second balance in the input inductor and result in distorted grid current shape. Their effect is especially evident in half-bridge converter, where input inductor operates with high voltage swing. The current sensorless control method proposed compensates this influence and allows achieving sinusoidal current shape. First, the phenomenon of current distortion was shown with numerical simulation in PSIM package. Experimental prototype rated for 350 W power was built to verify theoretical and simulation results. Experimental results are in good agreement with those obtained with simulation and theoretically. The PFC converter proposed features low cost of realization and can be used in consumer equipment for connection to the grid. accordance with real transistor parameters (Table II), the difference is only 24 ns that is 0.06% of switching period that is less than precision of the PWM module utilized in the experiments and thus can be neglected. The diode reverse recovery losses are not influencing volt-second balance of the inductor, but are a matter of capacitor discharge currents, and consequently can be neglected. Figure 7. Simulation results considering conduction losses: (a) light load condition-IM = 0.3 A; THD(Ic) = 91.2%; THD(Ig) = 2.9%; and (b) high load condition-IM =;4 A; THD(Ic) = 12.2%; THD(Ig) = 0.6%.Figure 8. Simulation results without consideration of conduction losses: (a) light load condition-IM = 0.3 A; THD(Ic) = 93.2%; THD(Ig) = 3.2%; and (b) high load condition-IM = 4 A; THD(Ic) = 48.5%; THD(Ig) = 37.4%.
