Introduction
I would like to introduce three.
Higher power density of power supply
By mounting the MLCC on a Si substrate of a standard CMOS process, we have realized a switched capacitor DC-DC converter with a high power density comparable to that of a deep trench.
Key component
By using a programmable digital gate driver, switching loss and overshoot optimization have been achieved.
Renewable energy
We proposed a method to solve the problem of partial shadows in photovoltaic power generation systems. It uses a back converter and a current inverter. Since no electrolytic capacitor is used, reliability is improved.
1) Integrated power supply
Higher power density of power supply
By mounting the MLCC on a Si substrate of a standard CMOS process, we have realized a switched capacitor DC-DC converter with a high power density comparable to that of a deep trench.
2) Gate electronics
Key component that connects high and low power
By using a programmable digital gate driver, switching loss and overshoot optimization have been achieved.
3) Solar power system
Solved the partial shadow problem
By using a back converter and a current inverter, an electrolytic capacitor is no longer required, and a simple and highly reliable photovoltaic power generation system has been realized.
-Let’s take a look at the chips we have
prototyped so far-
