Crucial issues facing the power electronics industry Do you understand the full impact of device capacitance on increasing switching power supply frequencies? Switching converter loss P (Switching loss)∝ f * (V * I *⊿T) ∝ Rg, Crss, ½ *Coss * V In general, higher switching frequencies allow power electronics circuits to be physically smaller and take up less area. However, as frequency increases the device on-resistance (Ron) becomes less important, and switching loss and driving loss become the dominant factors that determine overall circuit power loss. A power device’s capacitance...

Measure device junction capacitances accurately and automatically Measure capacitance at DC biases of up to 3 kV The drain or collector terminal of a power device is often exposed to high voltages when it is off, which determines the value of its junction capacitances at the moment it turns on. Therefore, understanding how device capacitance changes with applied voltage is very important for power electronics circuit designers. Knowing the true value of device capacitance at a specific voltage and the calculated voltage the device will experience in a circuit allows you to select a power...

Extensive range of capabilities meets both current and future capacitance measurement needs Easily measure normally-on device capacitances The faster switching frequencies and higher operating temperatures of normally-on power devices such as GaN FETs and SiC JFETs have made their use in power circuits more common. Due to their higher operating frequencies, it is extremely important to understand and characterize the capacitance characteristics of these normally-on devices so as to minimize switching losses. However, measuring the capacitance characteristics of a normally-on device adds an...
