SAN FRANCISCO — Alex Lidow has sold semiconductors in China for decades, starting at a company, called International Rectifier, that his father and grandfather founded in the Los Angeles area in 1947.
Now Mr. Lidow runs Efficient Power Conversion, which makes chips that manage electrical power in cars and other products. Efficient Power has a strong foothold in China, but has lately run into resistance from customers there that he traces to moves in Washington.
